## Events published

- `OnShowExtensionPage(GLAccountWhereUsed: Record "G/L Account Where-Used")` (integration): Integration event raised to allow extensions to handle custom setup page navigation. Enables custom object types to be included in the where-used analysis with specialized page handling.
  - subscribers: [Codeunit 18 "Financial Report Mgt."](../codeunit/18.md) OnShowExtensionPage, [Codeunit 5958 "Serv. Calc. G/L Acc.Where-Used"](../codeunit/5958.md) OnShowExtensionPage, [Codeunit 6789 "Withholding Tax Event Handler"](../codeunit/6789.md) OnShowExtensionPage
- `OnAfterCheckPostingGroups(var TempGLAccountWhereUsed: Record "G/L Account Where-Used" temporary; GLAccNo: Code[20])` (integration): Integration event raised after completing posting group analysis for a G/L account. Allows extensions to add custom table checks or modify the where-used results before display.
  - subscribers: [Codeunit 18 "Financial Report Mgt."](../codeunit/18.md) OnAfterCheckPostingGroups
- `OnAfterFillTableBuffer(var TableBuffer: Record "Integer")` (integration): Integration event raised after building the list of tables to check for G/L account usage. Enables extensions to add custom tables to the where-used analysis scope.
  - subscribers: [Codeunit 5958 "Serv. Calc. G/L Acc.Where-Used"](../codeunit/5958.md) OnAfterFillTableBuffer, [Codeunit 6789 "Withholding Tax Event Handler"](../codeunit/6789.md) OnAfterFillTableBuffer
- `OnBeforeShowGLAccWhereUsed(var GLAccountWhereUsed: Record "G/L Account Where-Used")` (integration): Integration event raised before displaying the where-used list to the user. Allows extensions to filter or modify the results before presentation.
- `OnShowSetupFormOnBeforeFAAllocationRunPage(var FAAllocation: Record "FA Allocation"; var GLAccountWhereUsed: Record "G/L Account Where-Used")` (integration): Integration event raised before opening the FA Allocation page from where-used navigation. Enables extensions to customize FA allocation page behavior or apply additional filters.
- `OnDeleteGLNoOnBeforeTempGLAccWhereUsedFindFirst(var TempGLAccountWhereUsed: Record "G/L Account Where-Used" temporary)` (integration): Integration event raised before checking if where-used entries exist during G/L account deletion validation. Allows extensions to perform custom where-used checks or modify validation logic.

## Procedures

- `ShowSetupForm(GLAccWhereUsed: Record "G/L Account Where-Used")`: Opens the appropriate setup form for the table referenced in the where-used entry. Navigates directly to the configuration page where the G/L account is being used.
- `DeleteGLNo(GLAccNo: Code[20]): Boolean`: Validates if a G/L account can be deleted by checking for usage in setup tables. Displays where-used information if account is referenced, preventing deletion.
- `CheckGLAcc(GLAccNo: Code[20])`: Analyzes where a G/L account is used and displays the results in the where-used list. Provides comprehensive analysis of account dependencies across all setup tables.
- `InsertGroupForRecord(var TempGLAccountWhereUsed: Record "G/L Account Where-Used" temporary; TableID: Integer; TableCaption: Text[80]; GLAccNo: Code[20]; GLAccNo2: Code[20]; FieldCaption: Text[80]; Key: array[8] of Text[80])`: Inserts a where-used entry group for a specific record using table metadata. Creates standardized entries for account usage tracking with table and field information.
- `CheckPostingGroups(GLAccNo: Code[20])`: Performs comprehensive analysis of posting group tables to identify where a G/L account is used. Scans all relevant setup tables using metadata relationships to build complete usage report.
- `AddTable(var TableBuffer: Record "Integer"; TableID: Integer)`: Adds a table to the buffer of tables to be checked for G/L account usage. Prevents duplicate entries when building the list of tables to analyze.

Plus 8 local procedures.

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. 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: "codeunit", object_name: "Calc. G/L Acc. Where-Used")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
