A Purchase Order (PO) or invoice failed to send to the SAP Business Network (BN) and returned the following error message:

"Invalid or unrecognized sender credentials"?

Response returned with status Code [401] of Type [Unauthorized] with message {Error:Invalid or unrecognized sender credentials. Please contact support with the Error Reference Number: ANERR-xxxxxxxxxxxxxxxxxxx for more details}.

This error indicates a mismatch in the Shared Secret configured between the SAP Ariba On-Demand site and the SAP Business Network. When the Shared Secret values are not identical across systems, authentication fails and documents cannot be transmitted successfully.

To resolve this issue, the Shared Secret must be reset and synchronized across all relevant environments:

• SAP Ariba On-Demand (Procurement and Sourcing / Reporting)

• SAP Business Network

Once the Shared Secret values match, outbound documents such as POs and invoices will resume transmission successfully.

If POs continue to fail with this error, please contact SAP Support to request a reset of the Shared Secret for your site.
