Base Application · Microsoft.Finance.GeneralLedger.Journal · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Finance/GeneralLedger/Journal/CheckGenJnlLineBackgr.Codeunit.al) · facts from BC29

## Events published

- `OnAfterCheckGenJnlLine(var GenJnlLine: Record "Gen. Journal Line"; var TempErrorMessage: Record "Error Message" temporary)` (integration): Integration event that occurs after checking a general journal line during background validation. Allows additional custom validation logic and error message collection.
- `OnBeforeCheckGenJnlLineDocBalance(GenJnlLine: Record "Gen. Journal Line"; var TempErrorMessage: Record "Error Message"; var IsHandled: Boolean)` (integration): Integration event that occurs before checking general journal line document balance validation. Allows custom handling of document balance validation logic during background processing.

## Procedures

- `RunCheck(Args: Dictionary of [Text, Text]; var TempErrorMessage: Record "Error Message" temporary)`: Executes comprehensive validation checks for general journal lines based on provided parameters. Performs document balance validation, recurring journal checks, and integration with standard line validation routines.

Plus 10 local procedures.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 11 "Gen. Jnl.-Check Line"](../codeunit/11.md) (3 calls: `RunGenJnlCheckLineCodeunit → (object)`, `RunGenJnlCheckLineCodeunit → GetErrors`, `RunGenJnlCheckLineCodeunit → SetLogErrorMode`)
- [Codeunit 28 "Error Message Management"](../codeunit/28.md) (2 calls: `PackErrorMessagesToResults → ErrorMessage2JSON`, `RunGenJnlCheckLineCodeunit → CollectErrors`)
- [Codeunit 9079 "Background Error Handling Mgt."](../codeunit/9079.md) (1 call: `RunCheck → GetDeletedDocumentsFromArgs`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC25, BC27

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## 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: "Check Gen. Jnl. Line. Backgr.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
