I read this screen shot differently.
it is just one PO, not multiple POs.
I see 3 item number, item 10 and 20 are zero quantity. which means an item was created and later deleted, which automatically opened the requisition again. it was new converted to item 20, which was then again deleted, then item 30 was created.
You can navigate into the PO by double clicking the PO number (if you have authorization)
by the way, you missed to ask a question.
