SP9 Patch 9 Approvals Not Processed

Gurus,

I'm facing an issue with Approvals in 7.2SP9 Patch9 where the approval tasks are not being considered. I started with a multiple stage approval workflow but have since reduced it to a single stage. It is an assignment approval task which retrieves the approver from the PVO. Nothing that I have tried results in the approval task being processed. Therefore I'm looking for suggestions.

Reviewing the idmv_approvals_<> views displays no entries. I can see the approvals in mxpv_approval with a status of 'wait'. Yet I am unable to determine what IdM is waiting for. Of course since the approvals are not processing there are no entries for the approver in the To Do tab.

Thoughts/suggestions are appreciated

Thanks
