3577154 - Inbound Delivery Allowing Excess Quantity Beyond Purchase Order Over Delivery Tolerance Limit

Symptom

The Inbound Delivery is allowing users to post quantities exceeding the Open Purchase Order (PO) quantity plus the defined Over Delivery Tolerance. For example, with a PO quantity of 10 and a 10% tolerance, the system should allow a maximum of 11 units. However, it is allowing higher quantities (e.g., 15).

Environment

SAP Business ByDesign.

Reproducing the Issue

  1. Go to Purchase Requests and Orders Work Center.
  2. Go to Purchase Orders View.
  3. Search for and Click Edit on Purchase Order ID ABC. (ABC represents Purchase Order ID).
  4. Navigate to the Items Tab.
  5. Under the Basic Data Sub Tab you will see that an Over Delivery of Z% has been maintained.
  6. Navigate to the Document Flow and open Supplier Delivery ID XYZ. (XYZ represents Supplier Delivery ID.)
  7. Navigate to the Line Items Tab.
  8. You will see that the fulfilled quantity is X, which is more than a Z% increase from the planned quantity of Y in the Purchase Order. (X represents Fulfilled Quantity, Y represents  Planned Quantity, Z represents  Over Delivery Tolerance).

Cause

The system is designed to allow flexibility in real-world procurement scenarios where suppliers may deliver more stock than planned.

The Over Delivery Tolerance setting does not apply to To-Stock items, which is why the system does not restrict the inbound delivery quantity. 

Resolution

This is standard system behaviour, as SAP allows inbound deliveries to receive more stock than the purchase order quantity for To-Stock items. 

This flexibility is intentional, as real-world scenarios may require receiving excess quantities.

The system does not enforce the purchase order quantity strictly during the inbound process, but it does notify users of discrepancies at the invoicing stage.

If the customer encounters an error while posting the supplier invoice due to excess quantity, they can resolve it by navigating to the Supplier Invoice screen, selecting the Exceptions tab, and accepting the Quantity Variance Exception before proceeding with the invoice posting.
