expression must return the interface type


<b>Dear XI experts,</b>

My scenario is ;

The input parameter for the RFC is send through a file and the response from the RFC comes into XI which is then written into a File (dummy). Finally I want to have Transformation(Message Mapping to IDoc) and send to Target system.

Pls advice, Anybody ??</b>
