System Application · System.Environment.Configuration · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/System%20Initialization/src/SystemInitializationImpl.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Access | Internal |
| SingleInstance | true |

## Event subscriptions

- InitCompany subscribes to Codeunit "Company Triggers" OnCompanyOpenCompleted
- SetCallerModuleOnBeforeInsertSignupContext subscribes to Table "Signup Context Values" OnBeforeInsertEvent
- CreateOrUpdateLoginInfoOnAfterLogin subscribes to Codeunit "System Initialization" OnAfterLogin

## Procedures

- `SetSignupContext(SignupContext: Record "Signup Context"; var SignupContextValues: Record "Signup Context Values")` (internal)
- `ShouldCheckSignupContext(): Boolean`
- `IsInProgress(): Boolean`
- `SetDisableSystemUserCheck(): Boolean` (internal)

Plus 4 local procedures.

## 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 150 "System Initialization"](../codeunit/150.md) (2 calls: `Init → OnAfterInitialization`, `InitCompany → OnAfterLogin`)
- [Codeunit 9026 "User Login Time Tracker"](../codeunit/9026.md) (2 calls: `CreateOrUpdateLoginInfoOnAfterLogin → CreateOrUpdateLoginInfo`, `Init → CreateEnvironmentLoginInfo`)
- [Codeunit 8711 "Telemetry"](../codeunit/8711.md) (1 call: `SetSignupContext → LogMessage`)
- [Codeunit 9010 "Azure AD User Management"](../codeunit/9010.md) (1 call: `Init → (object)`)

## Called by

- [Codeunit 150 "System Initialization"](../codeunit/150.md) (2 calls: `IsInProgress → IsInProgress`, `ShouldCheckSignupContext → ShouldCheckSignupContext`)

## 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: "System Initialization Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
