Error while posting the IDOC. Status message '56'

Hi,

I have a requirement where I will post an IDOC which inturn will split the original IDOC into child IDOCs based on the store value.

I am trying to post the IDOC in WE19. So, the Original IDOC is posted successfully with status '53'. Whereas, the child IDOCS finished with error. The status of the message is '56' and the error says 'EDI: Partner profile not available'. Could someone tell me what could be the reason for this..?

Actually, the IDOC was created by the Functional Consultant. So, should the partner profile creation also done by them or do we need to do anything to solve this problem.? Could someone answer me this question. Thanks in advance.

Best Regards,

Paddu.
