(This is the data returned to the procedure step or action block.) The receiving views in the procedure step may be export views or local views.
The following illustration explains the possible supplying and receiving views for view matching in the Procedure Action Diagram. In this figure, the Procedure Step ADD_CUSTOMER calls (uses) the External Action Block

The USE statement appears in the action diagram of the procedure step or action block. For more information, see the Design Guide.
