The SAP Business Network buyer account was previously configured to route supplier documents to the Ariba Buyer application URL, but all documents are failing with the error below:

Error: Authentication failed for Sender [AN01000000001] at Domain [NetworkID].
Please contact support with the Error Reference Number: XXXXXXXXXXXXXX for more details.

The supplier documents (invoices, service sheets, order confirmations) are failing in the supplier side with an Unauthorized error as well.

How is it possible to temporarily change the buyer account to route supplier documents to the Pending Queue instead?

In order to change supplier documents to be routed to the SAP Business Network's buyer account pending queue instead of the procurement system's URL, follow the steps below:

1. Sign-in to SAP Business Network
2. Click Administration > Configuration > cXML Setup
3. Remove the URL configured in the Profile URL field
4. Remove the URL configured in the Post Url field
5. Click Save

The error Authentication failed for Sender is usually caused by a mismatch in the shared secret between Ariba applications, so correcting the shared secret is the recommended action.

However, depending on the scenario and customer's business needs, one can also review the cXML configuration to have the supplier documents sent to the SAP Business Network account's pending queue instead, as instructed above.

See the section Using your account's pending queue in the SAP Business Network buyer administration guide for additional information on this feature.
