I'm new to workflow and we recently have a problem where the approver is trying to approve the leave request. He clicked on 'Execute' and gets the error above then it takes him to another screen and freezes up.
We are using WS04200009 Process Leave Request (with Approval) with approval task TS12400026.
Please let me know of any tcodes that I can use to diagnose the problem or better yet, a solution to this issue.
Thanks in advance!
