## 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 152 "User Permissions"](../codeunit/152.md) (2 calls: `CheckAndRaiseNotificationIfAppDBPermissionSetsChanged → CanManageUsersOnTenant`, `DisallowEditingPermissionSetsForNonAdminUsers → CanManageUsersOnTenant`)
- [Page 9846 "Changed Permission Set List"](../page/9846.md) (1 call: `AppDbPermissionSetChangedShowDetails → (object)`)

## Called by

- [Page 9802 "Permission Sets"](../page/9802.md) (6 calls: `OnDeleteRecord → DisallowEditingPermissionSetsForNonAdminUsers`, `OnInsertRecord → DisallowEditingPermissionSetsForNonAdminUsers`, `OnInsertRecord → VerifyPermissionSetRoleID`, …)
- [Page 9816 "Permission Set by User"](../page/9816.md) (5 calls: `FindUsers → GetOffset`, `FindUsers → IsInColumnsRange`, `FindUsers → IsPastColumnRange`, …)
- [Page 9874 "Permission Set By Sec. Group"](../page/9874.md) (5 calls: `FindSecurityGroups → GetOffset`, `FindSecurityGroups → IsInColumnsRange`, `FindSecurityGroups → IsPastColumnRange`, …)

## 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 Pages Mgt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
