Creating Purchase Order Commitments

Purchase order commitments are created through:

The commitment is derived from the value on the purchase order, and is the value of goods which have been ordered but for which no actual costs have yet been incurred.

The following purchase order data is significant in the creation and reduction of purchase orders:

Ensure that the commitment is created using the expected delivery date, not the date the purchase order was created.

The commitment values are updated each fiscal year and accounting period. They are calculated in the controlling area currency; conversion is based on the purchase order currency exchange rate.

Delivery Costs

The value for a purchase order commitment usually includes anticipated delivery costs. These costs are managed separately by the R/3 System. They are identified individually according to origin (for example, freight costs, duty costs, packaging, and so on). This distinction between the delivery costs and the purchase order itself ensures that you can clearly identify the different currencies in which the individual cost components are incurred

Multiple Account Assignment

In MM Purchasing, you can assign a purchase order item to more than one account assignment object. For example, you can distribute the costs for a purchase order item on several orders or cost centers. The system automatically updates the purchase order commitment on the relevant account assignment objects


You can change the account assignment for a purchase order item so that, for example, the costs are assigned to an item on order 2 instead of order 1. You can only do this if no actual costs have been yet incurred. This means that no goods receipt or invoice receipt may have occurred. The purchase order commitment is then displayed on the new account assignment object.

Multiple account assignment and reassignment are described in more detail in the MM - Purchasing Guide.
