Base Application · Microsoft.Utilities · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Utilities/OptionLookupBuffer.Table.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Caption | Option Lookup Buffer |
| TableType | Temporary |
| DataClassification | CustomerContent |

## 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 | ID | Integer | — | not editable; DataClassification SystemMetadata |
| 2 | Option Caption | Text[30] | Specifies the type of transaction you want to make. The value in this field determines what you can select in the No. field. | not editable; DataClassification SystemMetadata |
| 3 | Lookup Type | Enum "Option Lookup Type" | — | enum [Enum 1670 "Option Lookup Type"](../enum/1670.md); not editable; DataClassification SystemMetadata |

## Keys

- Key1: Option Caption (clustered)
- Key2: ID

## Events published

- `OnBeforeIncludeOption(OptionLookupBuffer: Record "Option Lookup Buffer"; LookupType: Option; Option: Integer; var Handled: Boolean; var Result: Boolean; RecRef: RecordRef)` (integration)
- `OnBeforeFormatOption(FieldRef: FieldRef; var Result: Text[30]; var IsHandled: Boolean)` (integration)
- `OnCreateNewOnBeforeInsert(var OptionLookupBuffer: Record "Option Lookup Buffer"; OptionID: Integer; OptionText: Text[30]; LookupType: Enum "Option Lookup Type")` (integration)
- `OnFillBufferLookupTypeCase(LookupType: Enum "Option Lookup Type"; var IsHandled: Boolean; var TableNo: Integer; var FieldNo: Integer; var RelationFieldNo: Integer)` (integration)
- `OnAutoCompleteOptionLookupTypeCase(LookupType: Enum "Option Lookup Type"; var OptionType: Text[30]; var IsHandled: Boolean)` (integration)

## Procedures

- `FillLookupBuffer(LookupType: Enum "Option Lookup Type")`
- `AutoCompleteLookup(var OptionType: Text[30]; LookupType: Enum "Option Lookup Type"): Boolean`
- `ValidateOption(Option: Text[30])`
- `FormatOption(FieldRef: FieldRef): Text[30]`
- `SetCurrentType(LineType: Option " ","G/L Account",Item,Resource,"Fixed Asset","Charge (Item)")`

Plus 3 local procedures.

## Relations

## Pages and codeunits on this table

- [Page 1670 "Option Lookup List"](../page/1670.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 9179 "Application Area Mgmt. Facade"](../codeunit/9179.md) (3 calls: `IncludeOption → IsFixedAssetEnabled`, `IncludeOption → IsItemChargesEnabled`, `IncludeOption → IsJobsEnabled`)

## Recent changes

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24, BC28

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: "Option Lookup Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
