|  | Method | [Table Method](../table/20144.md#fields) | Specifies the Method to get the value from table. It is required only when Source type is either "Current Record" or "table". |
|  | Field Name | `LookupTableFieldName` | Specifies the Source field of the Lookup. |
|  | Table Filters | `LookupTableFilters2` | Specifies the table filters applied on a table. |
|  | Table Sorting | `LookupTableSorting2` | Specifies the Sorting applied on table to get the lookup value. It is required only when Source type is either "Current Record" or "table". |
| Symbol | Name | `VariableName2` | Specifies the symbol name of the Lookup. |
| Table Attribtues | Table Name | `LookupTableName` | Specifies the Source table of the Lookup. It is required only when source type is either "Current Record" or "table". |
|  | Table Attribute Name | `AttributeName2` | Specifies the name of the table attribute. |

## 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 20130 "App Object Helper"](../codeunit/20130.md) (2 calls: `UpdatePageControls → GetFieldName`, `UpdatePageControls → GetObjectName`)
- [Codeunit 20133 "Script Symbols Mgmt."](../codeunit/20133.md) (2 calls: `SetCurrentRecord → SetContext`, `UpdatePageControls → GetSymbolName`)
- [Codeunit 20141 "Lookup Entity Mgmt."](../codeunit/20141.md) (2 calls: `HandleSourceTypeChange → DeleteTableFilters`, `HandleTableChange → DeleteTableFilters`)
- [Codeunit 20142 "Lookup Mgmt."](../codeunit/20142.md) (2 calls: `HandleSourceTypeChange → GetSourceTable`, `UpdatePageControls → GetSourceTable`)
- [Codeunit 20143 "Lookup Serialization"](../codeunit/20143.md) (2 calls: `UpdatePageControls → TableFilterToString`, `UpdatePageControls → TableSortingToString`)

## 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: "page", object_name: "Script Symbol Lookup Dialog")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
