How Purchase Order Commitments are Created

Use

The system calculates purchase requisition commitments (PReq commitments) from the remaining quantity of a purchase requisition. The system then multiplies this by the price from the purchase requisition.

The following data is relevant to creating the PReq commitment:

The value of the purchase requisition

Planned delivery date

Account assignment

Features

The system reduces PReq commitments on a quantity basis, using purchase orders referring to the corresponding purchase requisition. The system reduces a PReq commitment to zero using a purchase order with the full amount, or using a change in the purchase requisition.

You create a purchase requisition for five PCs at USD 1,500.00 each. This leads to a purchase order commitment for USD 7,500.00.

The purchasing department orders 3 PCs at USD 2,000.00 each. This causes a purchase order commitment for USD 6,000.00 (3 x USD 2,000.00).

The system reduces the purchase requisition commitment in proportion to quantity to USD 3,000.00 (3 x USD 1,500.00 = USD 4,500.00).

Integration

Purchase Requisitions using Consumption-Based Planning

The SAP Consumption-Based Planning component proposes the materials to be ordered. These proposals are based on previous consumption and existing warehouse stocks.

Manually Entered Purchase Requisitions

A purchase requisition is created manually in the requesting department. The person creating the purchase requisition defines what is to be ordered, in what quantity, and when the order is to occur.

For more information, see SAP Library under Logistics ® Materials Management ® Purchasing ® Purchase Requisitions.

Purchase Requisitions Created Automatically in Networks

You can create activities in the network as externally processed activities. The system automatically generates a purchase requisition from the data you maintain for the activity, when you save your entries.

To plan the material required for a project, you can assign the materials you need (to carry out the project) to business transactions. The system generates a purchase requisition if you assign material that is not in stock to a business transaction.

The resulting purchase requisition commitment also forms part of the availability control.
