## Properties

| Property | Value |
|---|---|
| Access | Internal |

## Event subscriptions

- DefaultOpenCompanySettings subscribes to Codeunit "Company Triggers" OpenCompanySettings
- DefaultOpenRoleBasedSetupExperience subscribes to Codeunit "System Action Triggers" OpenRoleBasedSetupExperience
- DefaultOpenGeneralSetupExperience subscribes to Codeunit "System Action Triggers" OpenGeneralSetupExperience
- DefaultOpenCopilotCapabilities subscribes to Codeunit "System Action Triggers" OpenCopilotCapabilities

## 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 154 "Navigation Bar Subscribers"](../codeunit/154.md) (4 calls: `DefaultOpenCompanySettings → OnBeforeDefaultOpenCompanySettings`, `DefaultOpenCopilotCapabilities → OnBeforeDefaultOpenCopilotCapabilities`, `DefaultOpenGeneralSetupExperience → OnBeforeDefaultOpenGeneralSetupExperience`, …)

## Recent changes

- 2026-07-23 [#9206 Added new privacy policy for BizChat depending on Microsoft Copilot 365 with EEA environments behavior changes](../../changes/bcapps/9206.md) (main, BC30, feature)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC29

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: "Navigation Bar Sub. Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
