AK9-P | Partially Accepted

AK9 “P” is used when the receiver can accept part of the functional group but rejects one or more transaction sets inside it. This usually means the envelope itself is readable, but some transactions fail syntax or implementation guide checks and do not proceed.

Step-by-step troubleshooting/fix

1) Identify which transaction sets were rejected by reviewing the transaction-level acknowledgments (AK5/IK5).

2) Compare the rejected ST/SE transactions to accepted ones to isolate what differs (loops, segment order, required elements).
