How to cancel a PO connected to a Work Order?

Hi all

From the requisition tab of a work order, a purchase requisition was made and a PO was created and released resulting in a “close” status of the requisition on the WO tab.

Now, I want to cancel the PO again, but I get the message that there are peggings connected to the PO line and I have to remove the pegging first. Problem is, I cannot do anything from the WO screen to remove the pegging, so I’m stuck.

How can I solve this?

thanks

Kurt
