Cancelling the previous workitem

[Amit Moghe]

Hi Workflow Gurus,

I am new to workflow and need some help.

I have a workflow for which I am using 'CHANGED' event of the business object BUS2012 (Purchase Order) as the triggering event. When a user changes a particular PO, this workflow starts. But before it is completed if there is another change to the same PO, then, one more workitem is started.

My requirement is that if there is change to the PO, then, it should delete the previous workitem and start a new workitem. Can you please advise me as to how this can be achieved?

Thanks in advance.

Regards,
Amit
