## Properties

| Property | Value |
|---|---|
| Caption | Data Exch. Line Def |
| 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 | Data Exch. Def Code | Code[20] | Specifies a code that identifies the data exchange definition. <small>via [Page 1212 "Data Exch Line Def Card"](../page/1212.md)</small> | TableRelation [Table 1222 "Data Exch. Def"](../table/1222.md) ("Data Exch. Def".Code); NotBlank |
| 2 | Code | Code[20] | Specifies the line in the file. <small>via [Page 1212 "Data Exch Line Def Card"](../page/1212.md)</small> | NotBlank |
| 3 | Name | Text[100] | Specifies the name of the mapping setup. <small>via [Page 1212 "Data Exch Line Def Card"](../page/1212.md)</small> |  |
| 4 | Column Count | Integer | Specifies how many columns the line in the bank statement file has. <small>via [Page 1212 "Data Exch Line Def Card"](../page/1212.md)</small> |  |
| 5 | Data Line Tag | Text[250] | Specifies the position in the related XML schema of the element that represents the main entry of the data file. <small>via [Page 1215 "Data Exch Line Def Part"](../page/1215.md)</small> |  |
| 6 | Namespace | Text[250] | Specifies the namespace (uniform resource name (urn)) for a target document that is expected in the file for validation. You can leave the field blank if you do not want to enable namespace validation. <small>via [Page 1212 "Data Exch Line Def Card"](../page/1212.md)</small> |  |
| 10 | Parent Code | Code[20] | Specifies the parent of the child that is specified in the Code field in cases where the data exchange setup is for files with parent and children entries, such as a document header and lines. <small>via [Page 1215 "Data Exch Line Def Part"](../page/1215.md)</small> | TableRelation [Table 1227 "Data Exch. Line Def"](../table/1227.md) ("Data Exch. Line Def".Code where("Data Exch. Def Code" = field("Data Exch. Def Code"))) |

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). 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: "Data Exch. Line Def")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
