How do I create a non-PO invoice in SAP Business Network?

NOTE: non-PO invoice means an invoice without the original Purchase Order, to which supplier is billing for.

To create a non-PO invoice:

1. Log in to your supplier account.
2. Navigate to your Workbench
3. Click Create
4. Select Non-PO Invoice.
5. Choose the Customer from the list
6. Select the Standard Invoice option.
7. Click Next.

In the invoice creation page:

1. Enter an invoice number, date, and other header-level information about the invoice in the summary area.
2. Enter header-Level taxes, shipping, special handling, attachments, and discounts as needed.
   
3. Enter any other information your customer requests in the Additional Information area.

You can invoice either or both goods and services in the Line Items section.

1. For goods, click Add > Add Material.
2. For services, click Add > Add General Service or Add > Add Labor Service.
3. Click Update. This will update details within the header section of your invoice.
4. Click Next and review
5. Click Submit.

Before you can start transacting with a customer on the SAP Business Network, you must first establish a trading relationship with your customer or have a unique customer code.
The following KBAs might also be helpful:

• How do I establish a trading relationship with a buyer?
• How do I contact my customer?

Also, when supplier cannot create non-PO invoice, because there is no option, or because it asks for customer code but supplier does not know the code, then supplier needs to contact to buyer. Buyer can allow/dis-allow for supplier to create non-PO invoice option.
