## Events published

- `OnBeforeLoad(MatrixColumns1: array[32] of Text[1024]; var MatrixRecords1: array[32] of Record "Dimension Value"; _Row: Code[20]; CurrentNoOfMatrixColumn: Integer; var IsHandled: Boolean)` (integration): Integration event raised before loading matrix data to enable custom matrix loading logic. Allows modification of matrix parameters and handling before standard matrix population occurs.

## Procedures

- `SetSelectedDimValue(DimValueCode: Code[20])`: Sets the selected dimension value code for matrix row filtering.
- `Load(MatrixColumns1: array[32] of Text[1024]; var MatrixRecords1: array[32] of Record "Dimension Value"; _Row: Code[20]; CurrentNoOfMatrixColumn: Integer)`: Loads dimension value combination matrix data with column headers and dimension restrictions. Populates the matrix cells with combination restriction indicators for visual display.
- `SetColumnVisibility()`: Sets the visibility of matrix columns based on the current number of active columns. Controls which matrix fields are displayed to optimize page performance and layout.

Plus 4 local procedures.

## Triggers

OnAfterGetRecord, OnInit, OnOpenPage

## 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: "page", object_name: "Dim. Value Combinations Matrix")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
