On the

Field Mapping

tab for the Target transformation, the fields shown in the

Target Fields

area are shown in a hierarchical structure. The target fields are determined by the request message structure of the operation selected for the Target transformation.

Each source object displays as a group in the

Input Fields

area. You can select fields in the

Input Fields

area to map the fields to the web service request. If the input fields include multiple input groups, map the groups to the corresponding nodes in the web service request. You need to map all of the fields that are required in the web service request.

If you map multiple source objects, you must assign primary and foreign keys to at least two groups. Ensure that the source data is sorted on the primary key for the parent object, and sorted on the foreign key and primary key for child objects.

In the

Mark as Key

dialog box, you can assign a field as primary or foreign key and select the related group, as shown in the following image:

Keys must be of data type Bigint or String.
