  - subscribers: [Codeunit 5341 "CRM Int. Table. Subscriber"](../codeunit/5341.md) OnAfterJobQueueEntryRun, [Codeunit 7237 "Master Data Mgt. Subscribers"](../codeunit/7237.md) OnAfterJobQueueEntryRun

## 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 28 "Error Message Management"](../codeunit/28.md) (3 calls: `OnRun → GetErrorsInContext`, `OnRun → PopContext`, `OnRun → PushContext`)
- [Codeunit 29 "Error Message Handler"](../codeunit/29.md) (1 call: `OnRun → RegisterErrorMessages`)
- [Codeunit 9805 "Job Queue Start Report Base"](../codeunit/9805.md) (1 call: `RunReport → (object)`)

## Called by

- [Codeunit 448 "Job Queue Dispatcher"](../codeunit/448.md) (1 call: `HandleRequest → (object)`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24, BC28

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: "Job Queue Start Codeunit")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
