ccBPM Scenario

Hi All,

I appreciate if you can help me to design one requirement.

I have IDOC-XI-Flat File requirement to process PO, and I need to co-relate the incoming records with PO.

I read few How-To document on IDOC. It talks about R/3-XI-R3, and that too not with ccBPM.

Can some one tell me the steps in ccBPM for this scenario? I think I need to also get acknowledgment to update the status record on IDOC along with co-relation.
