Internal Procurement 

Purpose

This scenario describes the procurement and management of a material that is obtained from an internal supplier.

Internal procurement using a purchase order has the following advantages over a stock transfer carried out without a PO:

"Internal Procurement" using a stock transport order (type of purchase order) with billing document and invoice describes the integrated use of the following R/3 components:

SAP Component

Functions

Purchasing

Create purchase requisitions,
Create and transmit purchase orders or SA delivery schedules

Warehouse Management/Inventory Management

Manage and valuate material stocks

Quality Management

Perform quality inspection of goods received against a purchase order

Invoice Verification

Check and post invoice with reference to purchase order

Prerequisites

Before you can use stock transport orders with a billing document and invoice, you need a vendor master record for the issuing plant.

The relevant Quality Management process flows in this scenario are described in detail in QM in Materials Management.

Process Flow

Purchase Requisition

Internal procurement begins with the generation of a purchase requisition:

Purchasing

  1. Once they have been created, you can assign requisitions to a source of supply, taking previous purchase orders or contracts into account in the process. If no suitable source of supply exists, you must:
    1. Issue requests for quotation to potential vendors
    2. Compare the quotations you receive in response
    3. Assign the purchase requisition to one of the quotations received

If required, the vendor must have been approved by Quality Management.

  1. Depending on the source of supply, you create and transmit one of the following documents:

– Scheduling agreement delivery schedule

– Purchase order or contract release order

  1. You monitor the order. The system is able to automatically print urging letters for you to send to the vendor, as required.

At this point you can enter an invoice based on the document data and park it so that you can process it later at the time of invoice verification.

  1. You can maintain vendor confirmations (e.g. acknowledgments and shipping notifications) relating to purchase orders or scheduling agreement delivery schedules. Such confirmations enable you to plan more precisely, since in this way the vendor provides you with increasingly reliable information on expected deliveries during the period between the PO date and the desired delivery date. Shipping notifications can be referenced at the time of goods receipt, allowing you to identify and investigate any quantity variances in good time.

Goods Receipt

As soon as the ordered goods arrive, you post the goods receipt. The material is thus recorded in the inventory management system. If the material is subject to a certificate requirement, you must confirm the existence of such a certificate.

The goods receipt triggers the following activities:

Invoice Verification

When the vendor’s invoice arrives, you match it with the purchase order or the goods receipt. After investigation and clarification of any discrepancies, you release the invoice for payment.

If the invoice verification process reveals any variances that the buyer needs to discuss with the vendor, you can park the invoice and continue processing it later.

Under certain circumstances, you can post an invoice as soon as you have posted the goods receipt (Evaluated Receipt Settlement). This allows you to settle up with regard to goods receipts without receiving an invoice from the vendor.

Storage

When the R/3 System releases the GR quantity after incoming inspection has given the all-clear, you place the goods into storage.

If the continuous inventory method is employed in your warehouse or stores, the system updates the necessary data at the time of stock putaway.
