# Codeunit 20142 "Lookup Mgmt."

> Codeunit 20142 "Lookup Mgmt." in INTaxEngine (Microsoft.Finance.TaxEngine.Core). 6 public procedures, 2 events. Introduced in BC29, still in BC30.

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

## Events published

- `OnGetLookupSourceTableID(CaseID: Guid; var TableID: Integer; var Handled: Boolean)` (integration)
  - subscribers: [Codeunit 20297 "Use Case Symbols Handler"](../codeunit/20297.md) OnGetLookupSourceTableID
- `OnGetSymbolDataType(ScriptSymbolLookup: Record "Script Symbol Lookup"; var Datatype: Enum "Symbol Data Type")` (integration)
  - subscribers: [Codeunit 20157 "Script Action Execution"](../codeunit/20157.md) OnGetSymbolDataType, [Codeunit 20297 "Use Case Symbols Handler"](../codeunit/20297.md) OnGetSymbolDataType

## Procedures

- `GetSourceTable(CaseID: Guid): Integer`
- `GetLookupDatatype(CaseID: Guid; ScriptID: Guid; ID: Guid): Enum "Symbol Data Type"`
- `ConvertLookupToConstant(CaseID: Guid; ScriptID: Guid; var ValueType: Option Constant,"Lookup"; var Value: Text[250]; var LookupID: Guid; var FormattedValue: Text; Datatype: Enum "Symbol Data Type"): Boolean`
- `ConvertConstantToLookup(CaseID: Guid; ScriptID: Guid; var ValueType: Option Constant,"Lookup"; var Value: Text[250]; var LookupID: Guid): Boolean`
- `OpenLookupDialogOfType(CaseID: Guid; ScriptID: Guid; ID: Guid; Datatype: Enum "Symbol Data Type")`
- `OpenLookupDialog(CaseID: Guid; ScriptID: Guid; ID: Guid)`

## 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 20132 "Script Data Type Mgmt."](../codeunit/20132.md) (9 calls: `ConvertLookupToConstant → ConvertLocalToXmlFormat`, `ConvertLookupToConstant → IsBoolean`, `ConvertLookupToConstant → IsDate`, …)
- [Codeunit 20141 "Lookup Entity Mgmt."](../codeunit/20141.md) (2 calls: `ConvertConstantToLookup → CreateLookup`, `ConvertLookupToConstant → DeleteLookup`)

## Called by

- [Page 20142 "Script Symbol Lookup Dialog"](../page/20142.md) (2 calls: `HandleSourceTypeChange → GetSourceTable`, `UpdatePageControls → GetSourceTable`)
- [Codeunit 20161 "Condition Mgmt."](../codeunit/20161.md) (1 call: `CheckCondition → GetLookupDatatype`)
- [Codeunit 20167 "Script Serialization"](../codeunit/20167.md) (1 call: `ConditionItemToString → GetLookupDatatype`)
- [Page 20190 "Conditions Dialog"](../page/20190.md) (1 call: `FormatLine → GetLookupDatatype`)
- [Page 20283 "Switch Statements"](../page/20283.md) (1 call: `OpenLookupDialog → OpenLookupDialog`)
- [Table 20191 "Tax Test Condition Item"](../table/20191.md) (1 call: `ValidateRHSValue → GetLookupDatatype`)

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