# Field to field mapping

When you map a source document field to a target document field, the values transfer as they are.

## Usage

Use field-to-field mapping when you want to import or export values exactly as the source document submits them.

> [!NOTE]
> **Note**
> 
> When the submitted data is an integer, decimal, string, or Boolean value, you can perform calculations with the data. Standard operations such as +, -, /, *, =, >, <, =>, =< are supported.

## Concept

A source document and a target document are required to set up a mapping activity. On the **Mapping Lines** page, you can map a field from the source document for each target document field. After mapping, the target field contains the same value as the source field. The **Expression Wizard** provides a convenient way for field-to-field mapping via the option **Map a Source Field**.
