SRM 7.0 Purchase Order Response always in status "In process" after confirm

Hello experts,

this problem is similar to the thread [SRM-SUS Purchase Order Response always "In Status"; which has been not finally responded.

My problem exists in an environment without SUS.

When a buyer confirms a PO response (POR) without any change, the system generates a new PO response with status "In process".  This new POR has also to be confirmed or rejected but the system generates again a new PO response with status "In process".

So we have a very nice loop for the purchaser without escape!

We are on SRM 7.0 SP07. The other thread mentioned that SAP will create some OSS notes, but I found nothing about this problem.

Any ideas?

Regards

Joe
