- Key2: Level, Code

## Events published

- `OnAfterSetDimSelectionChange(var DimensionSelectionBuffer: Record "Dimension Selection Buffer"; var TheDimSelectionBuf: Record "Dimension Selection Buffer" temporary)` (integration): Integration event raised after completing dimension selection change operations. Provides extensibility for custom processing after dimension selection modifications.
- `OnBeforeInsertDimSelBufForDimSelectionChange(var DimSelectionChange: Page "Dimension Selection-Change"; Dimension: Record Dimension; ObjectType: Integer; ObjectID: Integer; var IsHandled: Boolean)` (integration): Integration event raised before inserting dimension selection buffer records for dimension selection change operations. Allows custom validation and preprocessing before dimension buffer creation.
- `OnBeforeInsertDimSelBufForDimSelectionMultiple(var DimSelectionMultiple: Page "Dimension Selection-Multiple"; Dimension: Record Dimension; ObjectType: Integer; ObjectID: Integer; var IsHandled: Boolean)` (integration): Integration event raised before inserting dimension selection buffer records for multiple dimension selection operations. Allows custom validation and preprocessing before dimension buffer creation in multiple selection scenarios.
- `OnCompareDimTextOnBeforeSelectedDimFind(var SelectedDimension: Record "Selected Dimension"; ObjectType: Integer; ObjectID: Integer)` (integration): Integration event raised in CompareDimText before searching Selected Dimension records. Enables custom filtering and validation before dimension text comparison operations.
- `OnSetDimSelectionOnAfterSetDefaultRangeOnSelectedDimTable(var SelectedDimension: Record "Selected Dimension"; ObjectType: Integer; ObjectID: Integer)` (integration): Integration event raised after setting default range on Selected Dimension table during SetDimSelection operations. Allows additional filtering and validation before dimension selection processing.
- `OnSetDimSelectionOnBeforeSelectedDimInsert(var SelectedDimension: Record "Selected Dimension"; ObjectType: Integer; ObjectID: Integer)` (integration): Integration event raised before inserting Selected Dimension records during SetDimSelection operations. Enables custom validation and modification of dimension selection data before persistence.

## Procedures

- `SetDimSelectionMultiple(ObjectType: Integer; ObjectID: Integer; var SelectedDimText: Text[250])`: Opens dimension selection page for multiple dimension selection and updates the selected dimension text. Allows users to select multiple dimensions for analysis views and reporting scenarios.
- `SetDimSelectionChange(ObjectType: Integer; ObjectID: Integer; var SelectedDimText: Text[250])`: Opens a dimension selection page allowing users to change dimension selections for a specific object. Updates the selected dimensions text based on user choices and commits changes to the selected dimensions table.
- `CompareDimText(ObjectType: Integer; ObjectID: Integer; AnalysisViewCode: Code[10]; SelectedDimText: Text[250]; DimTextFieldName: Text[100])`: Compares current dimension selection text with stored dimension selections to ensure data consistency. Validates that the provided dimension text matches the dimensions stored in the Selected Dimension table.
- `SetDimSelection(ObjectType: Integer; ObjectID: Integer; AnalysisViewCode: Code[10]; var SelectedDimText: Text[250]; var DimSelectionBuf: Record "Dimension Selection Buffer")`: Updates dimension selections for a specific object based on user choices from the dimension selection buffer. Replaces existing selections with new ones and updates the dimension text representation.
- `SetDimSelectionLevelGLAcc(ObjectType: Integer; ObjectID: Integer; AnalysisViewCode: Code[10]; var SelectedDimText: Text[250])`: Sets dimension selection level for G/L Account based analysis with manual dimension selection. Provides G/L Account specific dimension management without automatic dimension assignment.
- `SetDimSelectionLevelGLAccAutoSet(ObjectType: Integer; ObjectID: Integer; AnalysisViewCode: Code[10]; var SelectedDimText: Text[250])`: Sets dimension selection level for G/L Account based analysis with automatic dimension assignment. Provides G/L Account specific dimension management with automatic dimension selection based on analysis view configuration.
- `SetDimSelectionLevelCFAcc(ObjectType: Integer; ObjectID: Integer; AnalysisViewCode: Code[10]; var SelectedDimText: Text[250])`: Sets dimension selection level for Cash Flow Account based analysis with manual dimension selection. Provides Cash Flow Account specific dimension management without automatic dimension assignment.
- `GetDimSelectionText(ObjectType: Integer; ObjectID: Integer; AnalysisViewCode: Code[10]): Text[250]`: Retrieves the text representation of currently selected dimensions for a specific object and analysis view. Builds dimension code list from Selected Dimension table records.

Plus 5 local procedures.

## Ask your agent

Procedure bodies are not stored here (D10). For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "table", object_name: "Dimension Selection Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
