The purchase order is a prerequisite for the cumulative updating of business volume figures. This section explains the price determination process for a purchase order and the how these functions interact with Subsequent Settlement.

Price determination for Agency Business documents is carried out in the same way.

When a purchase order is created, the system carries out price determination. This process is based on the price calculation carried out for the article. The calculation also defines which value is relevant to subsequent (end-of-period rebate) settlement accounting with respect to a condition (in the above example, this is the net net purchase price, NNPP).

Within the framework of price determination, the system checks whether any conditions have been agreed with the relevant vendor for the article in question (in the example: 5% discount and 1% surcharge) at the time of the purchase order. In this case, the valid conditions (4711) are taken into account in the purchase order and displayed.

If a condition belongs to a condition type for which a provision for accrued income is to be set up (that is, the condition involves subsequent settlement), the value of the provision (here: 1 % of 191.90 = 1.92) is displayed in the purchase order. In the case of condition types without provisions for accrued income, the value "0" is shown against the condition.

For weight- and volume-dependent condition records, the gross or net weight or the physical volume must be maintained in the article master record, purchasing info record, and/or the purchase order item, so that the system can access the condition record and update the business volume. In the case of points-dependent conditions, the points conversion factor must be maintained in the purchasing info record or in the purchase order.
