hi..

1. Purchase requisitions are internal documents you use to request your Purchasing department to procure a particular quantity of a material or a service for a particular date.

Purchase requisitions are either created manually by the department responsible or automatically by MRP.

A purchase order is a formal request to a vendor to supply certain goods or services under the stated conditions.

You can create purchase orders without reference, or with reference to a purchase requisition, a request for quotation, or another purchase order.

2.Purchase requisitions are either created manually by the department responsible or automatically by MRP.

3.you can create purchase orders without reference, or with reference to a purchase requisition, a request for quotation, or another purchase order.

4.Purchase Requisition is created first..

Hi,

Simplified Purchasing document flow

Reqirements(SD,PP,PM...) ---> Purchase Requisition --> Purchase order (sent to vendor) -- > Goods Receipt ( Receiving Material from Vendor) --> Invoice verification ( Invoice from vendor )

The requiremnts flow from different SAP modules to MM-Purchasing via MRP run (Material Requirements Planning) -> This creates Purchase Requisitions -> Based on the purchase requisition and information from purchasing info records the vendor is decided and a Purchase Order is created -> the Purchase order is sent to vendor and the vendor ships the material -> Goods Receipt is created in the SAP system for receiving the materials from Vendor -> Vendor sends an invoice for the Purchase order and it is entered into the SAP system using Invoice Verification

This is a very simplified version of flow in SAP MM-PURCHASING.

Thanks,
