# Codeunit 20301 "Tax Document Stats Mgmt."

> Codeunit 20301 "Tax Document Stats Mgmt." in INTaxEngine (Microsoft.Finance.TaxEngine.UseCaseBuilder). 2 public procedures, 1 events. Introduced in BC29, still in BC30.

INTaxEngine · Microsoft.Finance.TaxEngine.UseCaseBuilder · BC29-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Apps/W1/INTaxEngine/app/TaxEngine-UseCaseBuilder/src/Statistics/Codeunit/TaxDocumentStatsMgmt.Codeunit.al) · facts from BC29

## Events published

- `OnAfterFillTotalsByTaxType(var TotalsByTaxType: Dictionary of [Code[20], Decimal])` (integration)

## Procedures

- `UpdateTaxComponent(RecordIDList: List of [RecordID]; var ComponentSummary: Record "Tax Component Summary" temporary)`
- `ClearBuffer()`

Plus 8 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 20133 "Script Symbols Mgmt."](../codeunit/20133.md) (2 calls: `FillComponentBuffer → GetSymbolName`, `FillComponentBuffer → SetContext`)
- [Codeunit 20232 "Tax Type Object Helper"](../codeunit/20232.md) (2 calls: `FillComponentBuffer → GetComponentAmountFrmTransValue`, `FillTotalsByTaxType → GetComponentAmountFrmTransValue`)

## Called by

- [Page 20301 "Tax Component Summary"](../page/20301.md) (2 calls: `OnQueryClosePage → ClearBuffer`, `UpdateTaxComponent → UpdateTaxComponent`)

## Recent changes

- 2026-08-27 [#10516 Ruleset hardening: promote AL0468, AL0520, AL0589, AL0611, AL0749, AW0004 to Error](../../changes/bcapps/10516.md) (main, BC30, refactor)

## 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: "Tax Document Stats Mgmt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
