We assigned one employee to multiple users by mistake due to which in process requisition is not appearing in the notification summary window for approval.
Our EBS Release is 12.1.1. Any suggestions would be appreciated.
Do you mean that the notification is not appearing in both the users? It should be available in one of the users. There are 2 options..
1) Approve/Reject from the other user account where the notification exists.. anyways audit will show the person name only and should be fine
2) Ask the requestor to change the requisition(withdraw process) and then submit it again... (if you are using iProc).
