Q: In SAPgui, How can I tell if a Purchase order has closed, or a line item within it blocked?

Answer:

In SAPgui, display the PO:

1. Navigate to Role ZMIT > Purchasing > PO Displays > Display Indiv PO.
2. Enter the PO number and hit Enter.
3. Highlight the line item, then follow the menu path: Item > Statistics > Changes
4. For a closed PO, you will see entries such as Delivery Completed indicator, and Final Invoice indicator, as well as a Purchasing item change date. For a closed PO, the amount will no longer show up as a commitment on the DTR for the cost object.
