Which transaction code is used to create a Purchase Requisition (PR) and Purchase Order (PO)?

The transaction code used to create a Purchase Requisition (PR) and a Purchase Order (PO) is ME21N. This transaction is specifically designed for the creation of purchase orders in the SAP system, allowing users to input vendor information, item descriptions, quantities, and pricing details, which are essential to initiate the procurement process.

ME2N, which was selected, is actually used for displaying purchase orders based on various selection criteria. It allows users to view existing purchase orders, but it does not facilitate the creation of new orders or requisitions.

MIGO is another important transaction code, primarily used for goods movements within the system, such as goods receipts and goods issues. It is not focused on creating purchase requisitions or purchase orders.

IW41 is related to the maintenance of maintenance orders and confirms work done on maintenance tasks. It is used in different functional areas and does not pertain to purchase requisitions or orders at all.

In summary, ME21N is the correct choice for creating purchase requisitions and orders because it directly serves the purpose of initiating procurement activities within the SAP environment.
