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/components/TaxComponentFormula.Table.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| DataClassification | EndUserIdentifiableInformation |

## Fields

Explanation: the field's ToolTip in the code; without one, the ToolTip of a page control bound to the field (marked via the page); without that, its Caption (marked caption) when that differs from the name.

| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 1 | Tax Type | Code[20] | — |  |
| 2 | ID | Guid | — | DataClassification SystemMetadata |
| 3 | Expression | Text[250] | Specifies the numeric expression. <small>via [Page 20263 "Tax Component Formula Dialog"](../page/20263.md)</small> |  |
| 4 | Component ID | Integer | — | DataClassification SystemMetadata |

## Keys

- PK: ID (clustered)

## Procedures

1 local procedures, no public ones.

## Triggers

OnInsert, OnModify, OnDelete

## Referenced by

1 fields in 1 objects relate to this table (TableRelation or CalcFormula).

- [Table 20248 "Tax Component Formula Token"](../table/20248.md): Formula Expr. ID

## Pages and codeunits on this table

- [Page 20263 "Tax Component Formula Dialog"](../page/20263.md) (source table)

## 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 20232 "Tax Type Object Helper"](../codeunit/20232.md) (3 calls: `OnDelete → OnBeforeValidateIfUpdateIsAllowed`, `OnInsert → OnBeforeValidateIfUpdateIsAllowed`, `OnModify → OnBeforeValidateIfUpdateIsAllowed`)
- [Codeunit 20132 "Script Data Type Mgmt."](../codeunit/20132.md) (1 call: `ValidateExpression → GetTokensFromNumberExpression`)

## 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: "table", object_name: "Tax Component Formula")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
