## 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 6110 "GL Acc. Data Migration Facade"](../codeunit/6110.md) (22 calls: `MigrateGLAccountDetailsImp → CreateGLAccountIfNeeded`, `MigrateGLAccountDetailsImp → ModifyGLAccount`, `MigrateGLAccountDetailsImp → SetAccountCategory`, …)
- [Codeunit 4037 "Helper Functions"](../codeunit/4037.md) (15 calls: `CreateFixedAllocationAccountDistribution → CreateDimSet`, `CreateGLAccountBeginningBalanceImp → AreAllSegmentNumbersEmpty`, `CreateGLAccountBeginningBalanceImp → CreateDimSet`, …)
- [Codeunit 1797 "Data Migration Facade Helper"](../codeunit/1797.md) (4 calls: `CreateGLAccountBeginningBalanceImp → CreateGeneralJournalBatchIfNeeded`, `CreateGLAccountBeginningBalanceImp → CreateGeneralJournalLine`, `GenerateGLAccountTransactionsImp → CreateGeneralJournalBatchIfNeeded`, …)
- [Codeunit 1796 "Data Migration Error Logging"](../codeunit/1796.md) (3 calls: `CreateAllocationAccounts → SetLastRecordUnderProcessing`, `MigrateGLAccountDetailsImp → SetLastRecordUnderProcessing`, `MigrateStatisticalAccountDetailsImp → SetLastRecordUnderProcessing`)

## Called by

- Changed (declaration) in: none

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: "GP Account Migrator")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
