## Called by

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.

- [Page 9859 "Tenant Permission Subform"](../page/9859.md) (7 calls: `OnAfterGetCurrRecord → UpdatePermissionLine`, `OnAfterGetRecord → UpdatePermissionLine`, `OnInsertRecord → EmptyIrrelevantPermissionFields`, …)
- [Page 9856 "Metadata Permission Subform"](../page/9856.md) (2 calls: `OnAfterGetCurrRecord → GetObjectCaptionAndName`, `OnAfterGetRecord → GetObjectCaptionAndName`)
- [Page 9862 "Expanded Permissions"](../page/9862.md) (1 call: `OnAfterGetRecord → GetObjectCaptionAndName`)
- [Page 9865 "Permission Lookup List"](../page/9865.md) (1 call: `OnOpenPage → FillLookupBuffer`)

## Across versions

- Present in: BC23-30
- 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: "Permission Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
