| Caption | Field Mapping |
| SourceTable | Data Exch. Field Mapping Buf. |
| PageType | ListPart |

## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Group | Caption | [Caption](../table/1265.md#fields) | Specifies the caption of the field in Dynamics 365 that the node in the currency exchange rate file must map to. |
|  | Source | [Source](../table/1265.md#fields) | Specifies the XPath to the XML node that must be mapped to the specified field in Microsoft Dynamics 365. |
|  | Default Value | [Default Value](../table/1265.md#fields) | Specifies another value than the data in the field that will be exported, because you selected the Use Default Value check box. This field is only relevant for export. |
|  | Transformation Rule | [Transformation Rule](../table/1265.md#fields) | Specifies a rule for transforming imported text to a supported value before it can be mapped to a specified field in Microsoft Dynamics 365. When you choose a value in this field, the same value is entered in the Transformation Rule field in the Data Exch. Field Mapping table and vice versa. |

## 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: "page", object_name: "Data Exch. Setup Subform")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
