Variance in an Invoice Item
Use
The following blocking reasons exist for variances in invoice items:
The invoiced quantity is larger than the difference between the quantity delivered and that already invoiced. In the SAP System, a quantity variance is treated differently depending on the amount of the variance. The product of the order price and the variance quantity is used as the basis for determining whether the invoice is to be blocked.
Lower priced items are therefore allowed relatively large quantity variances, whereas more expensive items are allowed only very small variances.
The invoiced price (amount invoiced divided by the quantity invoiced) is not the same as the net order price.
The date of invoice entry is before the delivery date agreed in the purchase order. In the SAP system, schedule variances are treated differently depending on the value of the invoice items. The product of the invoice item value and the number of days variance is used as a basis for determining whether the invoice is to be blocked. Lower priced items are therefore allowed relatively large schedule variances, whereas more expensive items are allowed only very small variances. If an invoice refers to a scheduling agreement, the system does not check for schedule variances, as there is no unique delivery date in the scheduling agreement.
The ratio between the order price quantity and the order quantity in the invoice differs from the ratio at goods receipt (or it differs from the ratio in the purchase order, if no goods receipt has been entered so far).
If a material is defined as being relevant for quality management, goods receipts for this material are posted to stock in quality inspection. Invoices for the material are blocked until the inspection has been successfully completed.
If more than one goods receipt is posted for an order item, an inspection is carried out for every goods receipt. In Invoice Verification, the system reacts differently depending on whether goods-receipt-based Invoice Verification is active:
The invoice is blocked if the inspection has not been completed for the goods receipt.
The invoice is blocked if any goods receipts are still in quality inspection. If an invoice is posted before the goods are received, it cannot be blocked for quality inspection.

When Quality Management is active, we recommend you work with goods-receipt-based Invoice Verification. In addition to the fact that the only invoices blocked are those that refer to the exact goods receipt, this also ensures that an invoice cannot be posted before the goods receipt and thus before the quality inspection has taken place.
Integration
An invoice containing a blocking indicator is blocked for payment until you release it.
