Purchase requisition not released -> Workitem completed

Hi,

Overall Purchase Requisition workflow is resulted with error message in Return " Purchase requisition blocked "  and not released but workitem is completed.

I am using Business object BUS2105 Method release.  and not used any terminating event for this task.

When PR not released, work item should not get completed so that they can execute again.

Please guide me.

Thanks & Regards,

Priya
