Each step below will occur in SAP Ariba:

  1. Gerdau sends Purchase Order to supplier.
  2. Supplier sends Order Confirmation to Gerdau to confirm price and delivery date.
  3. Supplier sends Shipping Notice to Gerdau.
  4. Supplier sends Invoice to Gerdau – this must be sent through Ariba portal.  Please do not mail or email invoices to Gerdau.  They will not get processed.
  5. Gerdau enters Goods Receipts as items are delivered.
  6. For On-Site Services, Supplier will need to complete a Service Entry Sheet (SES) in the Ariba Network.
  7. Gerdau sends payment when Invoice Reconciliation is complete.  This process checks that the invoice has all the required information to match the Purchase Order for Payment.
  8. Important Note:  If invoice does not have all the required information then it will be sent back to the supplier for correction through the SAP Ariba Network.
