Assigning a Field in SAP XI Message Mappings

Use

Using the structure overview and the data-flow editor you can map source fields of the source structure to a target field.

Features

You can:

● Use drag and drop to select a source field in the structure overview and map it to a target field, or the other way around. The mapping editor displays this simple assignment in the data-flow editor.

● Drag a target field and one or more source fields from the structure overview to the data-flow editor. The data-flow editor automatically assigns the first source/target field pair. If a target field has already been mapped, then the mapping is displayed in the data-flow editor.

● Select a source and target field from the structure view by double-clicking. Note that you always transfer source fields to the data-flow editor by double-clicking. However, this is only possible for target fields if they have not already been assigned a source field. When you double click a target field that has already been assigned, the system navigates to the corresponding mapping.

In the data-flow editor you can then connect source fields with standard functions or with your own functions (see: Functions in the Data-Flow Editor). In the simplest instance, assign a source field to a target field. The value of the source field is then transferred to the target field at runtime.

A source field can also be mapped to multiple target fields. Simply define multiple target field mappings in which the source field is assigned to the respective target field.
