You must add the information service support data types to the
list of selectable data types in the process editor before you can create
variables for data sources, for set references, and for sets.
To add information service support types:
- Open your business process.
- Create information service support types.
- Right-click on the canvas and select Create Information Service
Support Types. This adds the information service support types,
namely tDataSource, tSetReference, and tSet to the list of selectable data
types. You only need to do this the first time you create an information service
activity.
