Workflow Admin in 4.6C - "No administrator found for the task"

[Namit Bhargava]

1. I have assigned myself as the Wf admin in Wf config (SWU3).
2. I have assigned all the SAP recommended roles to my profile - therefore
I have all the auth. in the system to change a work item (Autho. Object
S_WF_WI).
3. Now when I go to "Display a work item" (and I have already chosen
Technical View in Personal workflow settings) and go to Edit -> Change - I
get the message "No administrator found for the task" (Message no. 5W 141).
The work item status is "Ready". However if the work item status is
"Reserved" - then I am able to change the work item itself. If the work
item status is "Error" - then also I am able to change the work item. I
cannot change the work item having the status "Ready". Any guidance? This
is 4.6C; R/3 Support Package 44 for 4.6C. The task is defined as General
Task.
4. Point 1 & 2 were done a week ago - so the system is refreshed and it is
not a buffer issue.
 
Thanks & regards,
