No administrator found for the task

[Uday Malghan]

Hi,
 
We are in process of testing Custom Expense Request Approval workflow.  It
was copied from SAP standard template WF20000040.  We are using Deadline
monitoring for Manager's approval Task. Manger has two weeks to react on
the approval Task. If do not act by that time task will be forwarded to
Next level.
However when I login as workflow administrator and try to change deadline
times, system gives message 'No administrator found for the task'.
On workflow template screen I have defined myself as workflow
administrator.
 
Any clues? Am I missing any authorizations?
 
Thanks.
