In English: The supplier number (Lieferantennummer), your identification in the federal accounting system, is missing. For ebInterface 6.0 the portal answers EBI60-0012.

## Why it fails

- `Biller/InvoiceRecipientsBillerID` is missing or empty.

## How to fix it

- Give the supplier number the federal government assigned to you (eight digits, such as 50012345, found on the order). Without one, ask the ordering office for it.
