We have got small issue with EDI confirmation. We have got two organizations: ORG_A and ORG_B. As far as ORG_A is considered, EDI acknowledgments work fine. While accepting Purchase order with XML (no matter if it's Standard PO or Blanket Release) in ORG_B, Buyer has to reapprove (Accept or Reject) supplier's change, as their acknowledgment is treated as change. After buyer's acceptance supplier need to acknowledge purchase order again (it has got Requires Reapproval status), even if XML Acknowledgment has been sent.
Where should I look for issue's source? What might be the problem?
