I have here a simple integration process based on the <b>BPMPatternCollectTime.</b> I receive multiple idocs during a certain period of time, after that I map the idocs into a legacy format.
I have declared abstract interfaces for both structures and have linked these to container variables in the process.
When I want to activate the process I get the following error message from the transfromation step:
<u>Expression must return the interface type <b><Abstract source interface></b></u>
I have checked the interface mapping and message mappings and they both look Ok.
What else can be?
Thanks for any help.
