The PO and Invoice process in SAP Ariba involves the following key stages: SAP Ariba Training

1. Purchase Requisition (PR) Creation
2. Purchase Order (PO) Generation
3. PO Approval and Dispatch

2. Purchase Order (PO) Process in SAP Ariba

Step 1: Purchase Requisition (PR) Creation

The procurement process begins with a buyer creating a Purchase Requisition (PR) within SAP Ariba. This document includes details such as:

• The type of goods or services required
• Quantity and specifications
• Delivery dates and locations
• Estimated costs

The PR is submitted for approval based on predefined workflows and budget considerations.

Step 2: PO Generation and Approval

Once the PR is approved, SAP Ariba automatically generates a Purchase Order (PO). The PO contains:

• Buyer and supplier details
• Item descriptions and pricing
• Delivery instructions
• Payment terms

The PO is sent to the supplier via the SAP Ariba Network, ensuring seamless digital communication. SAP Ariba Online Training

Step 3: PO Confirmation by Supplier

The supplier reviews the PO and either accepts it, requests modifications, or rejects it. Upon acceptance, the supplier prepares for order fulfillment.

Step 4: Goods Receipt (GR) or Service Confirmation

Once the goods or services are delivered, the buyer records a Goods Receipt (GR) in SAP Ariba, confirming that the delivery matches the order. In the case of services, a Service Entry Sheet (SES) is submitted.

Step 5: Invoice Submission by Supplier

The supplier generates an invoice through the SAP Ariba Network, referencing the PO number. The invoice includes:

• Itemized costs
• Taxes and discounts
• Payment terms
• Bank details

SAP Ariba automatically performs a 3-way match, comparing the invoice against the PO and GR to ensure accuracy.

Step 6: Invoice Reconciliation and Approval

If discrepancies arise (e.g., incorrect pricing, quantity mismatch), SAP Ariba flags the invoice for review. The buyer can approve, dispute, or request corrections from the supplier.

Step 7: Payment Processing

Once the invoice is approved, it is sent for payment processing based on agreed payment terms (e.g., Net 30, Net 60). SAP Ariba integrates with enterprise resource planning (ERP) systems like SAP S/4HANA to ensure timely payments.
