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

## Procedures

- `GetAttributeName(AttributeID: Integer): Text[30]`
- `GetAttributeOptionValue(TaxType: Code[20]; AttributeID: Integer; var Value: Text[250])`
- `GetTaxRateAttributeLookupValue(TaxTypeCode: Code[20]; AttributeName: Text; var Value: Text): Boolean`
- `GetAttributeOptionIndex(TaxType: Code[20]; AttributeID: Integer; OptionText: Text[30]): Integer`
- `GetAttributeOptionText(TaxType: Code[20]; AttributeID: Integer; Index: Integer): Text[30]`
- `UpdateTaxAttributeFactbox(Record: Variant)`

Plus 5 local procedures.

## 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 20291 "Tax Rate Computation"](../codeunit/20291.md) (4 calls: `ModifyAttributeTaxTransactionValue → GetAttributeOptionText`, `UpdateTaxAttributeValue → GetAttributeName`, `UpdateTaxColumnValue → GetAttributeOptionIndex`, …)
- [Codeunit 20233 "Tax Setup Matrix Mgmt."](../codeunit/20233.md) (2 calls: `FillColumnValue → GetAttributeOptionText`, `UpdateOptionColumnValue → GetAttributeOptionIndex`)
- [Page extension 20232 "Customer Card Ext"](../pageextension/20232.md) (2 calls: `OnAfterGetCurrRecord → UpdateTaxAttributeFactbox`, `OnOpenPage → UpdateTaxAttributeFactbox`)
- [Page extension 20233 "Item Card Ext"](../pageextension/20233.md) (2 calls: `OnAfterGetCurrRecord → UpdateTaxAttributeFactbox`, `OnOpenPage → UpdateTaxAttributeFactbox`)

## 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 Attribute Management")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
