What is an SAP Business Network error (ANERR), and how do I resolve the issue?

You receive an ANERR message when an unexpected error occurs.

The following are common scenarios where you might receive an ANERR message:

• Clicking a link or button within your account
• Punch-in failure to your customer's procurement site (for example, creating a contract invoice or responding to a collaboration request)
• A PunchOut catalog connection failure

Messages appear in the following format:

Please contact support with the Error Reference Number: ANERR-100000000000000000XXXXXXXX

The ANERR number typically contains 26 digits after the hyphen. This number is a unique error identifier in the SAP Business Network logs, so you will never receive exactly the same ANERR number twice, even if you take the same steps to produce the error.

Oftentimes, the message preceding the ANERR number can help you determine the cause of the issue and how to resolve it. If you cannot determine the cause or solution based on the error message, first try clearing your browsing history/cookies, restarting the browser, and trying again. For more information on this process, please see How do I delete/clear my browser's recent history, cookies or cache?

If the issue persists, contact SAP Support and provide ALL of the following information:

• The full ANERR number
• The steps that you took before receiving the ANERR message
• Whether the error occurred only once or each time you took the steps

SAP Support will attempt to replicate the error and determine additional information related to the cause/resolution of the issue.
