Problem: “You must first modify the most recent entry for this item” displays on POAL when you try to zero out the accepted items, and the “Mod” column displays “N”.

Solution: (where PO number is 19886)

:SELECT PURCHASE.ORDERS WITH PO.NO LIKE 'P...19886'
>SELECT PURCHASE.ORDERS SAVING UNIQUE PO.ITEMS.ID
>SELECT ITEMS WITH ITM.PO.CURRENT.STATUS EQ ‘A’
>ELE -DICT ITEMS

Once here, go to field 116 (ITM.BACKORDER.TO.ITEMS.ID) and replace with null. This field must be blank for POAL to allow editing.

Now you can go to POAL and edit the accepted quantity.
