## Events published

- `OnFindDisableSelectedUseCases(var TaxUseCase: Record "Tax Use Case")` (integration)
- `OnFindDeleteSelectedUseCases(var TaxUseCase: Record "Tax Use Case")` (integration)

## Event subscriptions

- OnAfterDeleteTaxType subscribes to Table "Tax Type" OnBeforeDeleteTaxType
- OnBeforeValidateIfUpdateIsAllowed subscribes to Codeunit "Script Symbol Store" OnBeforeValidateIfUpdateIsAllowed
- OnBeforeModifyTaxUseCase subscribes to Table "Tax Use Case" OnBeforeModifyEvent

## Procedures

- `GetSourceTable(CaseID: Guid): Integer`
- `CreateRateColumnRelation(CaseID: Guid): Guid`: Rate Column Relation
- `DeleteRateColumnRelation(CaseID: Guid; ID: Guid)`
- `CreateUseCaseAttributeMapping(CaseID: Guid): Guid`: Use Case line
- `DeleteUseCaseAttributeMapping(CaseID: Guid; ID: Guid)`
- `CreateComponentCalculation(CaseID: Guid): Guid`: Component Calculation
- `DeleteComponentCalculation(CaseID: Guid; ID: Guid)`
- `CreateComponentExpression(CaseID: Guid; ID: Integer): Guid`
- `DeleteTaxComponentExpression(CaseID: Guid; ID: Guid)`
- `CreateTableRelation(CaseID: Guid): Guid`: TableRelation Functions
- `DeleteTableRelation(CaseID: Guid; var ID: Guid)`

Plus 2 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 20294 "Use Case Mgmt."](../codeunit/20294.md) (1 call: `OnAfterDeleteTaxType → DisableSelectedUseCases`)

## Called by

- [Codeunit 20361 "Tax Json Deserialization"](../codeunit/20361.md) (3 calls: `ReadAttributeMapping → CreateUseCaseAttributeMapping`, `ReadComponentCalculation → CreateComponentCalculation`, `ReadComponentCalculation → CreateComponentExpression`)
- [Page 20283 "Switch Statements"](../page/20283.md) (1 call: `OpenTableRelationDialog → CreateTableRelation`)
- [Table 20283 "Switch Case"](../table/20283.md) (1 call: `OnDelete → DeleteTableRelation`)
- [Table 20308 "Use Case Component Calculation"](../table/20308.md) (1 call: `OnDelete → DeleteTaxComponentExpression`)

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