## 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 1750 "Data Classification Mgt."](../codeunit/1750.md) (4 calls: `ShowNotificationIfThereAreUnclassifiedFields → AreAllFieldsClassified`, `ShowNotifications → DataPrivacyEntitiesExist`, `ShowSyncFieldsNotificationIfThereAreUnsynchedFields → GetLastSyncStatusDate`, …)
- [Codeunit 1306 "Company Information Mgt."](../codeunit/1306.md) (1 call: `ShowNotifications → IsEUCompany`)
- [Page 1751 "Data Classification Worksheet"](../page/1751.md) (1 call: `OpenClassificationWorksheetPage → (object)`)
- [Page 1752 "Data Classification Wizard"](../page/1752.md) (1 call: `OpenDataClassificationWizard → (object)`)

## Called by

- [Codeunit 1755 "Privacy Subscribers"](../codeunit/1755.md) (3 calls: `AfterExtensionIsInstalled → GetFilterTextForFieldValuesInTable`, `AfterExtensionIsInstalled → ShowNotificationIfThereAreUnclassifiedFields`, `AfterExtensionIsUninstalled → GetFilterTextForFieldValuesInTable`)
- [Codeunit 1430 "Role Center Notification Mgt."](../codeunit/1430.md) (1 call: `ShowNotifications → ShowNotifications`)

## 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: "Data Class. Notification Mgt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
