Setting the "Delivery Completed" indicator (technical field name: ELIKZ) in a purchase order (PO) item signals that the procurement process for that item is considered finished. Consequently, any remaining open quantity for the item is no longer considered an expected receipt by Material Requirements Planning (MRP), making the item irrelevant for the MRP run. While the indicator signals that no further deliveries are expected, the system does not by default prevent further goods receipts. Postings are still possible, for instance, if they fall within specified under/overdelivery tolerances.

C. The commitment for the PO item increases.

This is incorrect. Setting the "Delivery Completed" indicator reduces or clears the open financial commitment associated with the PO item, as the obligation is now considered fulfilled.

D. The order quantity of the PO item is still open.

This is incorrect. The primary function of the "Delivery Completed" indicator is to manually close the PO item, effectively setting the open order quantity to zero for planning purposes.

1. SAP Help Portal - S/4HANA - "Delivery Completed" Indicator:

"If the "delivery completed" indicator has been set for an item

the open purchase order quantity is zero

even if the full quantity has not been delivered. The item is then no longer taken into account by materials planning." This supports option B and refutes option D.

"Even if an item is considered closed

you can still post goods receipts against it. These goods receipts will be flagged as excess deliveries." This supports option A.

2. SAP Help Portal - S/4HANA - Commitment Management:

The documentation on commitment management explains that commitments from purchase orders are reduced by goods receipts and invoice receipts. Setting the "Delivery Completed" indicator finalizes the item

which leads to the clearing of any remaining commitment value. This refutes option C.
