Quantity Variance (SAP Library - Logistics Invoice Verification (MM-IV-LIV))

Quantity Variance

Definition

The difference between the quantity delivered and the quantity invoiced for goods received for a purchase order is the quantity still to be invoiced. A quantity variance exists if the quantity you are entering from the invoice does not match this open quantity.

Use

Quantity variances occur if the vendor:

Sends a partial invoice for one or more deliveries

In this case, the system expects to receive more invoices (or return deliveries).

Sends an invoice for a delivery that the goods receipt has not yet been posted for.

In this case, the system expects further goods receipts (or credit memos).

Special circumstances exist for goods-receipt based invoice verification:

If goods-receipt based Invoice Verification has been defined for an order item and the goods receipt has not yet been posted, the system does not allow you to post the invoice.

If goods-receipt based invoice verification has been defined for a purchase order item, a goods receipt has been posted, and an invoice is now entered for a larger quantity, the standard system is configured to display a warning message. This enables you to post a quantity larger than that received at the time of invoice receipt even when goods-receipt based invoice verification is active.

Note that no more goods receipts can be matched to this invoice. As a result, you can no longer tell from the purchase order history which goods receipt items belong to which invoice items.

You can control the system messages for goods-receipt-based invoice verification and purchase-order-based invoice verification separately in Customizing for Invoice Verification. In the standard system, both messages are configured as warning messages. For example, you can configure the message for goods-receipt-based invoice verification as an error message. This allows you to prevent payment for an invoice quantity that is larger than the delivered quantity in goods-receipt-based invoice verification.
