Invoice issue for 3rd party without shipping notification

[SAPSupport]

Hello SAP Team,

We are facing a major issue as part of Sales Processing using Third-Party without Shipping Notification (BDK) where system is copying the item quantity from Vendor invoice without any subsequent checks which is resulting in Invoices generated for a different quantity from Sales Order.

For example, we have a sales order where item 10 has quantity as 50. Order is saved, a purchase requisition was automatically created. Then the Purchase order generated with reference to requisition. 

The issue: Accidentally, we processed the Vendor invoice incorrectly with quantity as 50,000 instead of 50 by mistake. As soon as this was created, the Billing date on Sales order was updated and an Order related billing document was generated with 50,000 quantities. Now a customer invoice was incorrectly processed for 50,000 quantities, and the amount was automatically calculated as per the pricing condition records maintained in the system, rather than the price populated on the Vendor invoice.

Question: When creating the customer invoice in the Create Billing Documents app, shouldn't be there a safety checks or tolerance limit in these cases? Now SAP is automatically populating the quantity from Vendor invoice without any checks.

Please can you investigate the reason this has happened?

Thanks and regards,

Dear Customer,

From MM side there is no tolerance limit check for sales order quantity. For your information, the tolerance limit configuration for supplier invoice is Configuration (SSCUI) 101947. You can see there is no tolerance check for PO or service order quantity, so it does not take sales order quantity or purchase order quantity into consideration. 

Unfortunately there is no check on SD side for such cases as well. System using the information given by predecessor document. If there are 50 items delivered, from billing side the system will have to care about that there are 50 items invoiced. If the quantity changes (even drastically like in this case) system can not determine if this was by accident or on purpose. 

Best regards,
