## 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 20130 "App Object Helper"](../codeunit/20130.md) (1 call: `FormatLine → GetObjectName`)
- [Codeunit 20167 "Script Serialization"](../codeunit/20167.md) (1 call: `FormatLine → ConditionToString`)

## Called by

- [Codeunit 20365 "Use Case Archival Mgmt."](../codeunit/20365.md) (2 calls: `CopyUseCase → (object)`, `RestoreUseCase → (object)`)
- [Codeunit 20294 "Use Case Mgmt."](../codeunit/20294.md) (1 call: `CreateAndOpenChildUseCaseCard → (object)`)

## Across versions

- Present in: BC29-30
- 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: "page", object_name: "Use Case Card")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
