Purchasing flow in SAP.

Purchase requisition transactions

Step	Activity	Tcode in SAP	Remarks	Fiori App (To update soon)
1	Create Purchase Requisition	ME51K	Purchase Requisition created
2	Change Purchase Requisition	ME52K	Purchase Requisition changed

Key things to remember in purchase requisitions as a buyer.

• Account Assignment Category

–A key indicating whether an item is to be assigned to an auxiliary account (such as a cost center). The account assignment category determines which account assignment details are required for the item (for example, cost center or account number).

• Item Category

–An identifier indicating the characteristics of an item. The item category determines whether the following are mandatory or permitted for an item:

• Material number
• Additional account assignment
• Inventory management in the SAP system
• Goods receipt
• Invoice receipt

Purchase Order Process

• System-generated purchase order.
  • • A purchase requisition is generated via the Material Requirements Planning (MRP) process. A buyer converts the purchase requisition into a purchase order. The purchase order is subject to approval based on the release strategy. The buyer then sends the purchase order to the vendor.
    • Goods are shipped from the vendor, and the receipt of the goods is done with reference to the purchase order.
    • The invoice is received from the vendor. Invoices are entered with reference to a purchase order. The vendor is paid by accounts payable.

• Purchase order Process Flow

As a buyer, you should also be aware what are the different types of purchase document types created by your consultant. For eg, you may have a separate document type (Usually NB standard sap, but could be different based on need).

• NB – System generated
• MAN- Manually created
• RET- Returned to vendor PO
• CON- Consumables.
• AST -Asset purchase.

Each would ideally have its own number range,

Different Purchase order Scenarios you may face are as below.

Scenarios	Document Type	Description	Account Assignment Category	Description	Item Category	Description
Stock	NB or Custom	System-Generated or Manual Created				Standard
Subcontracting	NB or Custom	System-Generated or Manual Created			L	Subcontracting
