I have made the settings as synchronous in the Item category at app level in GTS 11, which I thought would keep the partner from getting blocked if it was changed in the document.
What I am seeing is that whenever I change the address to a BP such as the ship to the order gets blocked for SPL and in the audit trail it says that the address was changed manually.
Changing it to asynchronous seems to have the same behavior. Is there somewhere else I have missed a config setting?
