## Properties

| Property | Value |
|---|---|
| SingleInstance | true |

## Event subscriptions

- TaxTypesOnOpenPage subscribes to Page "Tax Types" OnOpenPageEvent
- OnAfterActionTaxTypesArchivedLogs subscribes to Page "Tax Types" OnAfterActionEvent (ArchivedLogs)
- OnAfterActionTaxTypeArchivedLogs subscribes to Page "Tax Type" OnAfterActionEvent (ArchivedLogs)

## Procedures

- `SetSkipTaxAttributeDeletion(NewSkipTaxAttribute: Boolean)`
- `GetSkipTaxAttribute(): Boolean`
- `SetSkipTaxComponentDeletion(NewSkipTaxComponent: Boolean)`
- `GetSkipTaxComponent(): Boolean`

## Called by

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 20297 "Use Case Symbols Handler"](../codeunit/20297.md) (2 calls: `OnBeforeTaxAttribtueDeleteEvent → GetSkipTaxAttribute`, `OnBeforeTaxComponentDeleteEvent → GetSkipTaxComponent`)
- [Table 20258 "Tax Type"](../table/20258.md) (2 calls: `OnDelete → SetSkipTaxAttributeDeletion`, `OnDelete → SetSkipTaxComponentDeletion`)

## 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: "Archival Single Instance")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
