When submitting an invoice, I receive the error VAT information required even though I already entered tax information.

Your buyer has enabled the two rules below, but they have not added a tax with the value VAT.

• Sub-rule Require VAT for rule Require suppliers to provide tax information in invoice.
• Require suppliers to choose from your list of valid tax values.

Since your buyer requires a value of VAT and is expecting a value from their list of valid taxes, the invoice returns an error because there is no VAT value available for you to select on their list of valid taxes.

You must contact your buyer to request one of the following two actions be taken:

1. Disable the sub-rule Require VAT for the rule Require suppliers to provide tax information in invoice. OR
2. Add a VAT value to their list of valid taxes.

Once one of these actions is completed, you must submit a new invoice with the proper tax information.

As Australia suppliers do not use VAT, if encountering the above error, another option to finish the validation is using ABN number as VAT.

1. Click the [user initials] on the top right corner of SAP Business Network home page.
2. Click Company Profile > Business Information tab.
3. Input your ABN number into ABN Number and Vat ID fields.
4. Tick the checkbox of VAT Registered.
5. Click on Save.
