# Codeunit 20235 "Use Case Data Type Mgmt."

> Codeunit 20235 "Use Case Data Type Mgmt." in INTaxEngine (Microsoft.Finance.TaxEngine.TaxTypeHandler). 1 public procedures. Introduced in BC29, still in BC30.

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/UseCaseDataTypeMgmt.Codeunit.al) · facts from BC29

## Procedures

- `GetAttributeDataTypeToVariableDataType(AttributeDataType: Option): Enum "Symbol Data Type"`

## 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) (4 calls: `InitTaxAttributes → GetAttributeDataTypeToVariableDataType`, `InitTaxColumn → GetAttributeDataTypeToVariableDataType`, `InsertTaxAttributes → GetAttributeDataTypeToVariableDataType`, …)
- [Codeunit 20233 "Tax Setup Matrix Mgmt."](../codeunit/20233.md) (2 calls: `FillColumnValue → GetAttributeDataTypeToVariableDataType`, `UpdateTaxConfigurationValue → GetAttributeDataTypeToVariableDataType`)
- [Table 20233 "Record Attribute Mapping"](../table/20233.md) (2 calls: `GetAttributeValue → GetAttributeDataTypeToVariableDataType`, `ValidateAttributeValue → GetAttributeDataTypeToVariableDataType`)
- [Codeunit 20237 "Tax Rates Export Mgmt."](../codeunit/20237.md) (1 call: `GetRateColumnValue → GetAttributeDataTypeToVariableDataType`)
- [Codeunit 20238 "Tax Rates Import Mgmt."](../codeunit/20238.md) (1 call: `UpdateRateColumnValue → GetAttributeDataTypeToVariableDataType`)
- [Codeunit 20291 "Tax Rate Computation"](../codeunit/20291.md) (1 call: `UpdateRateColumnSymbols → GetAttributeDataTypeToVariableDataType`)
- [Codeunit 20298 "Use Case Variables Mgmt."](../codeunit/20298.md) (1 call: `GetTaxAttributeValue → GetAttributeDataTypeToVariableDataType`)
- [Codeunit 20342 "Tax Document Subledger Posting"](../codeunit/20342.md) (1 call: `PopulateAttributeRateColumnVariables → GetAttributeDataTypeToVariableDataType`)
- [Codeunit 20343 "Tax Posting Buffer Mgmt."](../codeunit/20343.md) (1 call: `UpdateUseCaseVariables → GetAttributeDataTypeToVariableDataType`)
- [Table 20261 "Tax Transaction Value"](../table/20261.md) (1 call: `GetTransactionDataType → GetAttributeDataTypeToVariableDataType`)

## 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 Data Type Mgmt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
