1s 8.3 SCD report calculated fields. Data Composition System Expression Language (1Cv8)
In light of the upcoming release of 8.2.14, I will try to describe some new functions of the data composition system.
Open the data layout diagram, preferably in an external report, to make editing easier.
We add a dataset of the query type and write, either manually or using the query designer, a simple query:
1. Set up a request in the access control system.
2. Set up calculated fields in the access control system
3. Configure the data layout on the settings tab
4. Launch 1C Enterprise 8.2.14. Open the report. We form, we receive.
Description of the new functions themselves:
1. The current date()
Returns the system date. When composing a layout layout, in all expressions that are present in the layout, the CurrentDate() function is replaced with the value of the current date.
2. COMPUTEEXPRESSION()
Syntax:
CalculateExpression(,)
Description:
The function is designed to evaluate an expression in the context of some grouping.
The function takes into account the selection of groupings, but does not take into account hierarchical selections.
The function cannot be applied to a grouping in the group selection of that grouping. For example, in selecting the Nomenclature grouping, you cannot use the expression CalculateExpression("Sum(SumTurnover)", "TotalTotal") > 1000. But such an expression can be used in hierarchical selection.
If the end record precedes the start record, then it is considered that there are no records for calculating detailed data and calculating aggregate functions.
When calculating interval expressions for a grand total (the Grouping parameter is set to GrandTotal), it is assumed that there are no records for calculating detailed data and calculating aggregate functions.
Layout linker when generating a function expression CalculateExpression, if the ordering expression contains fields that cannot be used in grouping, replaces the function CalculateExpression on NULL.
Options
Type: Line. The expression to be evaluated.
Type: Line. Contains the name of the grouping in the context of which the expression is to be evaluated. If an empty string is used as the grouping name, the calculation will be performed in the context of the current grouping. If the GeneralTotal string is used as the group name, the calculation will be performed in the context of the grand total. Otherwise, the calculation will be performed in the context of the parent grouping with the same name.
For example:
Sum(Sales.SumTurnover)/Calculate("Sum(Sales.SumTurnover)", "Total")
IN in this example the result will be the ratio of the sum by field Sales.AmountTurnover grouping records to the sum of the same field in the entire layout;
Type: Line. The parameter can take the following values:
· Grand total— the expression will be calculated for all grouping records.
· Hierarchy— the expression will be evaluated for the parent hierarchical record, if there is one, and for the entire grouping, if there is no parent hierarchical record.
· Grouping— the expression will be evaluated for the current group grouping record.
· GroupingNonResource— when calculating a function for a group record by resources, the expression will be calculated for the first group record of the original grouping.
When calculating a function CalculateExpression() with meaning GroupingNonResource for group records that are not grouped by resources, the function is calculated in the same way as it would be calculated if the parameter value was equal to the value Grouping.
The data composition layout builder, when generating a data composition layout when outputting the resource field by which grouping is performed to the layout, places an expression in the layout that is calculated using the function CalculateExpression() , indicating the parameter GroupingNonResource. For other resources, the usual resource expressions are placed in the resource grouping.
Type: Line. Indicates from which record the fragment should begin, in which aggregate expression functions should be calculated, and from which record to obtain field values outside of aggregate functions. The value can be one of the following:
· First
· Last (Last)
· Previous
· Next (Next)
· Current
· LimitingValue(BoundaryValue) LimitingValue
Type: Line. Indicates to which record the fragment should be continued, in which the aggregate functions of the expression should be calculated. The value can be one of the following:
· First. It is necessary to obtain the first grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the beginning of the grouping. The resulting value must be an integer greater than zero. For example, First(3) - receiving the third record from the beginning of the grouping.
If the first record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get First(4), then it is considered that there are no records.
· Last (Last). You need to get the last grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the end of the grouping. The resulting value must be an integer greater than zero. For example, Last(3) - receiving the third record from the end of the group.
If the last record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get Last(4), then it is considered that there are no records.
· Previous. You need to get the previous grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset back from the current grouping record. For example, Previous(2) - getting the previous from the previous record.
If the previous record goes beyond the grouping (for example, for the second grouping record you need to get Previous(3)), then the first grouping record is obtained.
When retrieving the previous record for a grouping total, it is considered that the first record is obtained.
· Next (Next). You need to get the next grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset forward from the current grouping entry. For example, Next(2) - getting next from the next record.
If the next record goes beyond the grouping, then it is considered that there are no records. For example, if there are 3 entries and the third entry receives Next() , then it is considered that there are no entries.
When the next record is received for the grouping total, it is considered that there is no record.
· Current. You need to get the current record.
When retrieving for a grouping total, the first record is obtained.
· LimitingValue(BoundaryValue). The need to obtain a record by the specified value. After the word LimitingValue in brackets you need to indicate the expression with the value of which you want to start the fragment, the first ordering field.
The first record whose ordering field value is greater than or equal to the specified value will be returned as the record. For example, if the Period field is used as the ordering field, and it has the values 01/01/2010, 02/01/2010, 03/01/2010, and you want to get LimitingValue(DateTime(2010, 1, 15)), then a record with the date 02/01/2010 will be received.
Type: Line. Lists expressions, separated by commas, that describe the ordering rules. If not specified, then the ordering is performed in the same way as for the grouping for which the expression is evaluated. After each expression you can specify a keyword Age(for ordering in ascending order), Descending(for ordering in descending order) and Auto-order(to order reference fields by the fields by which you want to order the referenced object). Word Auto-order can be used as with the word Age, so with the word Descending.
Type: Line. Same as parameter Sorting. Used to organize hierarchical records. If not specified, the layout builder generates the ordering according to the ordering specified in the parameter Sorting.
Type: Line. Specifies the rule for determining the previous or next record in case there are several records with the same ordering value:
· Separately indicates that a sequence of ordered records is used to determine the previous and next records. Default value.
· Together indicates that the previous and next records are determined based on the values of the ordering expressions.
For example, if the resulting sequence is ordered by date:
| № | date | Full name | Meaning |
| 1 | January 01, 2001 |
Ivanov M. |
10 |
| 2 | 02 January 2001 | Petrov S. | 20 |
| 3 | January 03, 2001 | Sidorov R. | 30 |
| 4 | 04 January 2001 | Petrov S. | 40 |
Separately, That:
§ the previous entry to entry 3 will be entry 2.
Current, Current(accordingly, parameters Start And End), then for record 2 this fragment will consist of one record 2. The expression will be equal to 20.
If the parameter value is Together, That:
§ the previous entry to entry 3 will be entry 1.
§ if the calculation fragment is defined as Current, Current(accordingly, parameters Start And End), then for record 2 this fragment will consist of records 2 and 3. Expression CalculateExpression("Sum(Value)", Current, Current) will be equal to 50.
When specifying a parameter value equal to Together, in parameters Start And End you cannot specify an offset for positions First, Last, Previous, Next.
CalculateExpression("Sum(SumTurnover)", "First", "Current")
If you want to get the grouping value in the previous line, you can use the following expression:
CalculateExpression("Rate", "Previous")
List new functions:CalculateExpressionWithGroupArray(,) -
The function returns an array, each element of which contains the result of evaluating an expression for grouping by the specified field.
CalculateExpressionWithGroupValueTable(,) -
The function returns a table of values, each row of which contains the result of evaluating expressions for grouping by the specified field
ValueFilled() - Returns True if the value is different from the value of this type default, other than NULL, other than empty reference, other than Undefined. Boolean values are checked for NULL values. Strings are checked for the absence of non-whitespace characters
Format(, ) - Receive a formatted string of the passed value. The format string is set in accordance with the format string of the 1C:Enterprise system.
Substring(, , ) - This function is designed to extract a substring from a string.
Line Length() - The function is designed to determine the length of a string. Parameter is a string expression
Line() - If an array is passed as a parameter, the function returns a string containing string representations of all array elements, separated by "; " characters. If a table of values is passed as a parameter, the function returns a string containing string representations of all rows of the table of values, with the cell representations of each row separated by ";" characters, and the rows by a newline character. If an element's string representation is empty, then a string is displayed instead of its representation.
In this short note I want to show how you can summarize values at various levels of grouping in a report using a data composition system.
As shown in the image, only at the “Item Groups” grouping level, the “Order” resource is calculated, it displays how much needs to be ordered for the current item group based on certain conditions:
This value can only be calculated at this grouping level, since there are no values above or below to calculate. For example, at the level of detailed records, there is no data on the maximum quantity in a group, because this data is valid only for the group as a whole, and not for its individual components.
Accordingly, now it is necessary to calculate the totals for the above groupings (“Warehouses”, “Warehouse Types”) and the overall total.
To do this, use the function CalculateExpressionWithGroupArray:
EVALUATE EXPRESSIONWITHGROUPARRAY (EVALEXPRESSIONWITHGROUPARRAY)
Syntax:
EvaluateExpressionWithGroupArray(,)
Description:
The function returns an array, each element of which contains the result of evaluating an expression for grouping by the specified field.
The layout compositor, when generating a layout, converts function parameters into terms of data composition layout fields. For example, the Account field will be converted to DataSet.Account.
Layout compositor when generating expressions for output custom field, whose expression contains only the function CalculateArrayWithGroupArray(), generates an output expression in such a way that the output information is ordered. For example, for a custom field with the expression:
CalculateExpressionWithGroupArray("Amount(AmountTurnover)", "Counterparty")
The layout builder will generate the following expression for output:
ConnectRows(Array(Order(CalculateExpressionWithGroupingValueTable("View(Sum(DataSet.AmountTurnover)),Sum(DataSet.AmountTurnover)",,"DataSet.Account"),"2")))
Options:
Type: String. The expression to be evaluated. String, for example, Amount(AmountTurnover).
Type: String. Grouping field expressions – expressions of grouping fields, separated by commas. For example, Contractor, Party.
Type: String. An expression describing the selection applied to detail records. The expression does not support the use of aggregate functions. For example,DeletionFlag = False.
Type: String. An expression describing the selection applied to group records. For example, Amount(AmountTurnover) > &Parameter1.
Example:
Maximum(CalculateExpressionWithGroupArray("Amount(AmountTurnover)", "Counterparty"));
A detailed description of the function syntax can be found at http://its.1c.ru/db/v837doc#bookmark:dev:TI000000582
Now, for the calculation, we duplicate the “Order” field, with different values “Calculate by...”, using the following expressions, note that in each higher level the values of the levels below the groupings are used.
As a result, we get the following construction:
One of the most convenient and unique development tools in 1C is the data composition system (DCS). Few in any information systems developers can create reports without writing any code. This mechanism was developed to simplify and speed up the development of reporting forms and give more opportunities to users in working with the output data. The latter is very highly valued by advanced users, who thanks to this can independently customize the report to their own needs, without waiting for the actions of developers.
Creating a report in 1C via SKD
The process of developing a report using ACS can be divided into the following stages:
- Creating a request. You can write a request manually or do without code using a convenient interface;
- Setting up the report. Select fields, totals, groupings, parameters, report design;
- After this, all we have to do is connect the resulting report to the configuration in any available way.
Despite the ability of users to customize reports on the access control system, they must be created through the configurator.
Let's look at an example of creating an external report on an access control system:
Now we go to 1C, open our report to make sure the actions taken are correct. All data is reflected, groupings can be collapsed and expanded. As you can see, the access control system allows you to receive full-fledged reports without writing code, with the exception of non-standard requirements. Considering that most reports have a similar structure, knowledge of the access control system will significantly reduce the time for developing these objects.
This mechanism has become very popular due to its support for extensive reporting capabilities. Moreover, not only developers, but also ordinary users can use them.
ACS capabilities
There are situations when we have made a report, and then a user comes and asks to make a small modification. For example, instead of product names, display article numbers. SKD allows users to make such modifications independently using the “More” - “Change option...” button.
The window that opens is similar to the settings window in the report in the configurator, and it also has similar functions. To solve the task, the user must go to the “Fields” tab and change the “Nomenclature” field. This edit field opens by double-clicking and the “Select...” button becomes available.
The window that opens gives us the opportunity to select any value that will appear in the “Nomenclature” field. Some fields have a plus sign on the left - the developer has placed links in these fields, which means we can see their details. We open “Nomenclature” and see the article that we need. Select it and select it.
The window for changing report options contains many useful functions of the data composition system. For example, the user can independently change the order of groupings, add selection, or apply conditional design. We complete the editing and generate a report - as you can see, the entire product range is now displayed in the form of articles.
The SKD 1C:Enterprise 8.3 mechanism also has expanded functionality for developers. When developing the report, we used only 2 tabs - “Data sets” and “Settings”, but there are many more of them in the ACS. To use all the functions of the data composition system, you need to understand what each of the tabs is for:
- Data sets – all queries involved in generating the report are listed here;
- Data set connections – used to build connections between different queries from the first tab;
- Calculated fields – a list of added fields not from the query. Most often used in cases where, based on the values of several fields, you need to get 1 value from the request;
- Resources. In 1C, this is the name for the fields for which you need to know the results. Resources support various arithmetic operations– amount, quantity, maximum and others;
- Options. They are used if to generate a report it is necessary for the user to enter certain data - date, divisions or nomenclature, for example;
- Layouts. Designed for cases where users want to see a uniquely designed report. You can create a separate place for signatures or a new top part of the report - all this can be done here;
- Nested diagrams. They are needed when your report must contain data from other reports;
- Settings. The section declares the displayed fields, groupings, and configures appearance report.
The number of possibilities incorporated into the ACS mechanism by developers is large, but many of them are used extremely rarely. Even experienced 1C programmers may not use some functions after years of work. To start working successfully in the access control system, it is enough to know the basic concepts and frequently used settings. In rare cases, documentation will come to the rescue.

Data composition system 1C 8.3 for beginners: counting the results (resources)
The purpose of this lesson will be:
- Write a report that displays a list of products (Food directory), their calorie content and taste.
- Group products by color.
- Learn about summarizing (resources) and calculated fields.
Create a new report
As in previous lessons, we open the database " Deli"in the configurator and create a new report through the menu" File"->"New...":
Document type - external report:
In the report setup form, write the name " Lesson3" and press the button " Open data composition diagram":
Leave the default schema name and click the " Ready":
Adding a request through the constructor
On the tab " Data set" click green plus sign and select " Add Dataset - Query":
Instead of writing the request text manually, we run it again query constructor:
On the "tab" Tables"drag the table" Food" from the first column to the second:
Select from the table " Food"fields that we will request. To do this, drag and drop the fields" Name", "Taste", "Color" And " Calorie content" from the second column to the third:
It turned out like this:
Press the button " OK" - the request text was generated automatically:
Creating report presentation settings
Go to the tab " Settings" and click on magic wand, to call settings designer:
Select the report type " List..." and press the button " Further":
Drag from the left column to the right the fields that will be displayed in the list and click " Further":
Drag from the left column to the right field " Color" - it will happen grouping lines in the report. Click " OK":
And here is the result of the designer’s work. Hierarchy of our report:
- the report as a whole
- grouping "Color"
- detailed entries - lines with food names
Save the report (button diskette) And without closing We will immediately open the configurator in user mode. It turned out like this:
Changing the order of columns
But let's let's change the order columns (up and down arrows) so that it looks like the figure below:
Let's save the report and open it again in user mode:
Great, that's much better.
Let's sum up the calorie content
It would be nice to summarize the calorie content of foods by group. To see the sum of the calorie content of all products, say, white or yellow. Or find out the total calorie content of all products in the database.
For this purpose, there is a mechanism for calculating resources.
Go to the tab " Resources"and drag the field" Calorie content"(we are going to summarize it) from the left column to the right.
In this case, in the field, select the expression from the drop-down list " Amount(Calorie)", since the total will be the sum of all elements included in the total:
We save and generate a report:
We now have results for each of the groups and for the report as a whole.
Let's sum it up (average) in terms of calories
Now let's make it appear in another column average calorie content of products by groups and in the report as a whole.
You cannot touch the existing “Calorie” column - the total is already displayed in it, so let's create another field, which will be an exact copy of the "Calorie" field.
To create such a “virtual” field, we will use the mechanism calculated fields.
Go to the tab " Calculated fields" and press green plus sign:
In a collumn " Data path"we write the name of the new field ( seamlessly, without spaces). Let it be called " Average Calorie Content", and in the column " Expression"we write the name of an existing field on the basis of which the new field will be calculated. We write there " Calorie content". Column " Heading" will be filled in automatically.
We have added a new field (" Average Calorie Content"), but it will not appear in the report by itself - you need to either call again settings designer("magic wand") or add this field manually.
Let's do it second way. To do this, go to the tab " Settings", select " Report"(after all, we want to add the field as a whole to the report), select the tab at the bottom" Selected fields"and drag the field" Average Calorie Content"from the left column to the right:
It turned out like this:
We save and generate a report:
The field has appeared and we see that its values are the values of the "Calorie" field. Great!
To do this, we will again use the mechanism already familiar to us resources(summarizing). Go to the tab " Resources"and drag the field" Average Calorie Content"from the left column to the right:
Moreover, in the column " Expression"choose" Average(AverageCalorie)":
We save and generate a report:
We see that for the groups, that is, for each color, and for the report as a whole, the average value was calculated absolutely correctly. But they are present extra entries for individual products (not groups) that I would like to remove from the report.
Do you know why they appeared (values not by group)? Because when we added the field " Average Calorie Content"in the report settings, in the second step we selected the entire report and this new field ended up in the element " Detailed records".
Let's fix the error. To do this, go back to the tab " Settings", select " Detailed entries" first from above (step 2) and then " Detailed entries"from below (step 3), go to the bookmark" Selected fields" and we will see in its right column the element " Auto".
Element " Auto" - this is not one field. These are several fields that fall here automatically based on higher-level settings.
To see what these fields are, click on the element " Auto" right button and select " Expand":
Element " Auto" expanded into the following fields:
And here is our field" Average Calorie Content"which came here from the point " Report" when we dragged him there. Just let's remove check the box next to this field to remove its output.
1. Calculate (Eval)- is intended to evaluate an expression in the context of some grouping. The function is used for compatibility with previous versions of the platform. It is recommended to use the CalculateExpression function instead.
Syntax:
Calculate(Expression, Grouping, CalculationType)
Options :
- Expression(Line). Contains a calculated expression;
- Grouping(Line). Contains the name of the grouping in the context of which the expression is to be evaluated. If an empty string is used as the grouping name, the calculation will be performed in the context of the current grouping. If the GrandTotal string is used as the group name, the calculation will be performed in the context of the grand total. Otherwise, the calculation will be performed in the context of the parent grouping with the same name.
For example:
Sum(Sales.SumTurnover) / Calculate("Sum(Sales.SumTurnover)", "Total").
In this example, the result will be the ratio of the amount for the "Sales.AmountTurnover" field of the grouping record to the amount of the same field in the entire layout. - Calculation type(Line). If this parameter is set to "TotalTotal", the expression will be calculated for all grouping records. If the value of the parameter is "Grouping", the values will be calculated for the current grouping group record.
Syntax:
CalculateExpression(Expression, Grouping, CalculationType, Start, End, Sort, HierarchicalSort, ProcessingIdenticalOrderValues)
Options :
- Expression(Line). Contains a calculated expression;
- Grouping(Line). Contains the name of the grouping in the context of which the expression is to be evaluated. If an empty string is used as the grouping name, the calculation will be performed in the context of the current grouping. If the GrandTotal string is used as the group name, the calculation will be performed in the context of the grand total. Otherwise, the calculation will be performed in the context of the parent grouping with that name;
- Calculation type(Line). If this parameter is set to "TotalTotal", the expression will be calculated for all grouping records. If the value of the parameter is "Grouping", the values will be calculated for the current grouping group record. If the parameter is set to "Non-Resource Grouping", then when calculating the function for a group record by resource, the expression will be evaluated for the first group record of the original grouping. When evaluating the CalculateExpression function with the value "GroupingNonResource" for group records that are not groupings by resource, the function is evaluated in the same way as it would be evaluated with the value of the "Grouping" parameter. The data composition layout builder, when generating a data composition layout when outputting a field - a resource by which grouping is performed, to the layout, outputs to the layout an expression calculated using the CalculateExpression function with the specified "GroupingNon-Resource" parameter. For other resources grouped by resource, normal resource expressions are returned. If the parameter is set to "Hierarchy", then the expression must be evaluated for the parent hierarchical record, if there is one, and for the entire grouping, if there is no parent hierarchical record. The layout builder, when generating an expression for the % in Hierarchy Group field, generates an expression containing the relationship of the resource expression to the CalculateExpression function for the resource expression being calculated for the current grouping with calculation type Hierarchy.
- Start. Indicates from which record the fragment should begin, in which aggregate expression functions should be calculated, and from which record to obtain field values outside of aggregate functions. A string containing one of:
- "First" It is necessary to obtain the first grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the beginning of the grouping. The resulting value must be an integer greater than zero. For example, First(3) – receiving the third record from the beginning of the grouping. If the first record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get First(4), then it is considered that there are no records.
- "Last" You need to get the last grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the end of the grouping. The resulting value must be an integer greater than zero. For example, Last(3) – receiving the third record from the end of the group. If the last record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get Last(4), then it is considered that there are no records.
- "Previous" You need to get the previous grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset back from the current grouping record. For example, Previous(2) – getting the previous from the previous record. If the previous record is outside the grouping (for example, the second grouping record requires getting Previous(3)), then the first grouping record is obtained. When receiving the previous record for the grouping total, the first record is obtained.
- "Next" You need to get the next grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset forward from the current grouping entry. For example, Next(2) – getting the next from the next record. If the next record goes beyond the grouping, then it is considered that there are no records. For example, if there are 3 entries and the third entry receives Next, then it is considered that there are no entries. When the next record is received for the grouping total, it is considered that there is no record.
- "Current". You need to get the current record. When retrieving for a grouping total, the first record is obtained.
- "BoundaryValue". The need to obtain a record by the specified value. After the word LimitingValue in parentheses, you need to indicate the expression with the value of which you want to start the fragment, the first ordering field. The first record whose ordering field value is greater than or equal to the specified value will be returned as the record. For example, if the Period field is used as the ordering field, and it has the values 01/01/2010, 02/01/2010, 03/01/2010, and you want to get the LimitingValue(DateTime(2010, 1, 15)), then a record with the date 02/01 will be obtained. 2010.
- End. Indicates to which record the fragment should be continued, in which the aggregate expression should be calculated. A string containing one of:
- "First"
- "Last"
- "Previous"
- "Next"
- "Current".
- "BoundaryValue".
- Sorting. A string that lists the expressions, separated by commas, in the direction of which the sequence should be ordered. If not specified, then the ordering is performed in the same way as for the grouping for which the expression is evaluated. After each expression, you can specify the keyword Ascending, for ordering in ascending order, Descending, for ordering in descending order, Auto-Ordering, for ordering the reference fields by the fields by which you want to order the object being referenced. The word Auto Order can be used with both the word Ascending and the word Descending.
- HierarchicalSorting. Similar to sorting. Used to organize hierarchical records. If not specified, the layout compositor generates the ordering according to the ordering specified in the Sort parameter.
- Processing Same Values of Order. A string containing one of:
- "Together" means that a sequence of ordered records is used to determine the previous and next records;
- "Separately" means that the previous and next records are determined based on the values of the ordering expressions;
1. January 01, 2001 Ivanov M. 10
2. January 02, 2001 Petrov S. 20
3. January 02, 2001 Sidorov R. 30
4. January 03, 2001 Petrov S. 40
When using processing of identical values of the order "Separately", the previous one for record 3 will be record 2, and when using "Together" - record 1. And the fragment for the current record for record 2 for "Separately" will be record 2, and for "Together" - records 2 and 3. Thus, the total for the current record for “Separately” will be 20, and for “Together” - 50. When “Together” is specified in the Start and End parameters, you cannot specify an offset for the positions “First”, “Last”, "Previous", "Next". The default value is "Separate".
Obtaining the ratio of the amount for the "Sales.AmountTurnover" field of a grouping record to the amount of the same field in the entire layout:
Sum(Sales.SumTurnover) / CalculateExpression("Sum(Sales.SumTurnover)", "Total").
This example calculates the value of the current hierarchy:
Choice
When Level() > 0
Then EvaluateExpression("Reference", "Hierarchy")
Otherwise Null
End
Notes:
The function takes into account the selection of groupings, but does not take into account hierarchical selections. The function cannot be applied to a grouping in the group selection of that grouping. For example, in selecting the Nomenclature grouping, you cannot use the expression CalculateExpression("Sum(SumTurnover)", "TotalTotal") > 1000 . But such an expression can be used in hierarchical selection. If the end record precedes the start record, then it is considered that there are no records for calculating detailed data and calculating aggregate functions. When calculating interval expressions for a grand total (the Grouping parameter is set to "GrossTotal"), it is assumed that there are no records for calculating detailed data and calculating aggregate functions. When generating an expression for the CalculateExpression function, the layout compositor, if the ordering expression contains fields that cannot be used in grouping, replaces the CalculateExpression function with NULL.
3. Evaluate Expression With Group Array (EvalExpression With Group Array) - the function returns an array, each element of which contains the result of calculating an expression for grouping by the specified field.
Syntax:
CalculateExpressionWithGroupArray (Expression, GroupFieldExpressions, SelectRecords, SelectGroups)
Options :
- Expression(String) - the expression to be evaluated. For example, "Amount(AmountTurnover)";
- FieldExpressionsGroups
- Selection of Records
- Selection of Groupings- selection applied to group records. For example: "Amount(AmountTurnover) > &Parameter1".

The layout builder, when generating expressions for the display of a custom field whose expression contains only the CalculateArrayWithGroup function, generates the display expression so that the data displayed by the views and the data are ordered.
For example, for a custom field with the expression:
CalculateExpressionWithGroupArray("Amount(AmountTurnover)", "Counterparty")
The layout builder will generate the following expression for output:
ConnectRows(Array(Order(CalculateExpressionWithGroupingValueTable("View(Sum(DataSet.AmountTurnover)), Amount(DataSet.AmountTurnover)", "DataSet.Account"), "2")))

- Expression(String) - the expression to be evaluated. A line can contain multiple expressions separated by commas. After each expression there may be an optional keyword AS and the name of the value table column. For example: "Counterparty, Amount (AmountTurnover) As Sales Volume."
- FieldExpressionsGroups- expressions of grouping fields, separated by commas. For example, "Counterparty, Party";
- Selection of Records- an expression applied to detail records. For example, "Deletion Flag = False." If in this parameter an aggregate function is used, an error will occur when composing the data;
- Selection of Groupings- selection applied to group records. For example: "Amount(AmountTurnover) > &Parameter1".
Calculate Expression With Grouping Table of Values ("Account AS Counterparty, Amount (Amount Turnover) AS Sales Volume", "Account")
The result of this function will be a table of values with columns Counterparty and Sales Volume, which will contain counterparties with their sales volumes.
The layout compositor, when generating a layout, converts function parameters into terms of data composition layout fields. For example, the Account field will be converted to DataSet.Account.
For example, a custom field with the expression:
CalculateExpressionWithGroupValueTable("Account, Amount(AmountTurnover)", "Account")
The layout builder will generate the following expression for output:
ConnectRows(GetPart(Order(CalculateExpressionWithGroupValueTable("DataSet.Account, DataSet.AccountRepresentation, Sum(DataSet.AmountTurnover), View(DataSet.AmountTurnover), DataSet.OrderingField", "DataSet.Account"), "5, 1, 3" ), "2, 4"))
