Approval preview for PO is empty.
we're suffering this issue :
we implemmented BADI n-step approval workflow (WS14000145) for PO.
Everything works fine, that's to say, approvers receive their workitems and finally Po is approved.
Meanwhile Po is in approval status, approval preview shows all approvers involved. But when PO is approved, approval preview is empty. So, user can't see which approvers gave their ok.
We debugged our system, we found out that in table APPROVER_LIST, field APPROVAL_STATE in the container for approvers is '2' ( not instanced) instead of being '0' (accepted). If we change this value to '0' in debug mode, then approval preview shows approvers list properly.
How can we fix that? Why after accepting PO, is approval_state '2'?
We have SRM server 550, and SP is 8.
Thanks in advance.
