Purchase requisitions
The purchase requisition procedure is designed for the nonpurchasing user who may not know the standard procedures in purchasing. For example, engineers can order material or services without understanding the entire purchasing process. Purchase requisitions are used to specify nonsystem planned requirements for various types of items, including inventory items, cost items, and service items. You cannot use generic items, and list items (except for kit items) on requisitions.
Purchase requisitions are created in the same way as all other buy and sell documents, such as purchase orders and sales orders. However, there is one significant difference: on a requisition, the item code and buy-from business partner codes can be blank. Therefore, the requester can make a request for a new item or make a request from a new buy-from business partner.
