  - subscribers: [Codeunit 20345 "Tax Posting Handler"](../codeunit/20345.md) OnAfterOpenPostingSetup

## Event subscriptions

- OnAfterActionUseCases subscribes to Page "Tax Types" OnAfterActionEvent (UseCases)

- `IndentUseCases(CaseID: Guid; var PresentationOrder: Integer)`
- `EnableSelectedUseCases(var TaxUseCase: Record "Tax Use Case")`
- `DisableSelectedUseCases(var TaxUseCase: Record "Tax Use Case")`

## 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.

- [Page 20310 "Use Cases"](../page/20310.md) (2 calls: `OnAfterActionTaxTypeUseCases → (object)`, `OnAfterActionUseCases → (object)`)
- [Page 20308 "Use Case Card"](../page/20308.md) (1 call: `CreateAndOpenChildUseCaseCard → (object)`)

## Called by

- [Codeunit 20292 "Use Case Entity Mgmt."](../codeunit/20292.md) (1 call: `OnAfterDeleteTaxType → DisableSelectedUseCases`)
- [Codeunit 20361 "Tax Json Deserialization"](../codeunit/20361.md) (1 call: `ImportUseCases → IndentUseCases`)
- [Codeunit 20366 "Tax Engine Assisted Setup"](../codeunit/20366.md) (1 call: `SetupTaxEngineWithUseCases → IndentUseCases`)

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: "Use Case Mgmt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
