multiple source messages in transformation step in bpm

15 Views

Hello,

I am using a transformation step in bpm, I have two source messages and 1 target message, I got an error 'expression must return the interface type XXXX(in source message)', I checked my source message in interface mapping and the container element, the types do match.

All the interfaces in the OM as well as in the bpm container definition are of type abstract.

It seems to have something to do with the interfaces belonging to different software components?

I declared a usage dependency from one swcv (holding the bpm) to another (holding the abstract interfaces which cause the error in the transformation step), so that I can reference them in the bpm.

I thought it might have something to do on how the message interfaces are selected in the operation mapping. so I tried to select the messages through the depencency path, but that was of no help either.

Have I been clear?

Any ideas?

Thanks

Matthias
