Reproducing the Issue

  1. Go to Purchase Requests and Orders work center
  2. Select Purchase Orders
  3. Search for the third party purchase order
  4. Under General Tab, the purchasing unit and buyer responsible field is empty


You have configured that the Buyer responsible for the purchase order to be picked from the preceding document Purchase request.

But in Purchase request, the Purchasing Unit is not determined, hence the Buyer Responsible also could not be determined.

In Organizational Work Distribution Rule, you have maintained the wrong site(Purchasing unit) which does not belong to the buying company of the Purchase request/Purchase Order. Hence system was not able to identify the correct site/purchasing unit and thus the buyer responsible was not determined.


Kindly maintain the correct site(purchasing unit) which belongs to the buying company of the purchase documents in the Organizational Work Distribution Rule and the employee responsible for that purchasing unit in Employee work distribution rule. Also ensure that validity is correct.

Then create the documents from scratch without copying and the data should be correctly determined.
