Determine Input and Output Requirements for External Action Blocks

Determine the data the action block will receive from the CA Gen generated application, the data that must be returned to the CA Gen generated application, and the procedures that will be required to implement the external action block.

CA Gen uses the views defined in the external action block to generate the interface routine. The import and export views shown in the interface routine are supplied by the CA Gen procedure step or action block that uses the external action block. The import views define the data that is passed from the CA Gen generated application to the interface routine. The export views define the data returned to the CA Gen generated application from the interface routine.
