Why am I seeing an unexpected error (ANERR)?

Error: An unexpected error occurred. If you need assistance, Contact SAP Support with the Error Reference Number:[ANERR error number]

An unexpected error can occur when:

• Multiple browser windows with SAP Ariba pages are open
• Multiple users are connected to the same account at the same time. As a matter of best practice and system security, user credentials (usernames and passwords) should not be shared among multiple individuals for access. Each user should access the system using their own unique credentials to avoid conflicts and ensure proper session management.
• The previous session was not logged out properly and a new session is opened
• An expired link (for example, from a password reset email) is being used to log in

To resolve this error:

1. Clear browser cache and cookies and browsing history on your internet browser.
2. Close all browser windows.
3. Open a new browser window and log into your account via an SAP Ariba login page:
   • To access Ariba Proposals & Questionnaires directly, go to https://proposals.seller.ariba.com
   • To access SAP Business Network, go to https://supplier.ariba.com

If this error persists, contact SAP Support and provide the ANERR number, brief descriptions of what you are trying to do and the step by steps screenshot showing the exact steps up to the point the error message appears.
