SAP Create purchase order

A purchase order (PO) is the formal document ordering goods/services from a vendor. This guide shows how to create one in SAP GUI (ME21N).

Quick answer

Ensure the material and vendor master data exist and are complete.

Key takeaways
  • Select the order type (e.g. standard PO) and enter the vendor.
  • Add item lines: material (or short text), quantity, plant, delivery date.
  • This guide shows how to create one in SAP GUI (ME21N).
  • Watch out: the account assignment decides whether this becomes stock or somebody cost, and it is not easily changed.

Step by step

  • Enter transaction ME21N.
  • Select the order type (e.g. standard PO) and enter the vendor.
  • Add item lines: material (or short text), quantity, plant, delivery date.
  • Check pricing/conditions and the account assignment (stock vs consumption).
  • Save; the PO number is assigned and (if configured) it enters a release strategy.

Notes and tips

Ensure the material and vendor master data exist and are complete. For consumables, set the correct account assignment (cost center/order). If a release strategy applies, the PO must be approved before it can be issued. In Fiori, use the "Create Purchase Order" app for the same task.

Common pitfalls

  • Following steps without understanding the concept.
  • Skipping testing in a non-production system.
  • Applying blindly to a different scenario.
