Assigning a Field (SAP Library - SAP Exchange Infrastructure (BC-XI))

Assigning a Field

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 do the following:

Use Drag&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 field/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: Data-Flow Editor Functions). In the simplest instance, simply assign a source field to a target field. The value of the source field is then transferred to the target field at runtime.

Note

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.

Icon Colors

Color	Meaning
White	Attribute or element not assigned
Red	Attribute or element must be assigned to complete the mapping
Yellow	Attribute or element has already been assigned but the corresponding mapping in the data-flow editor is not complete
Green	Mapping to target field complete

Furthermore, collapsed target field names in the mapping editor are displayed in red if target field mappings for subnodes of the marked field name are still missing.

The colors used for the data-flow objects in the data-flow editor have the same meanings as those used above.
