When I try to register to view a sourcing event, I get the following error message:
Your company has already connected with this buyer company using a different account and Ariba Network ID (ANID) than the one you are trying to log into. To connect with this buyer company, you need to log into the already connected account. Please contact your company's account administrator and request that they create you as a new user under ANID (ANID).

If you believe you already have a username associated with the connected ANID, please refer internally to your company's account administrator to confirm the correct username to use.

If you do not have a username associated with the connected ANID, please follow these steps below to create a new username and access the event:

1. Return to the previous page and click Sign Up
2. Uncheck the box next to Use my email as my username
3. Create a username that is different than your existing username
   • Usernames are not required to be valid email addresses, but they do have to look like them
   • Ex: If your email is first.lastname@company.com, use first.lastname1@company.com
4. Enter a new password in the New Password and Confirm Password fields
   • Passwords must contain a minimum of eight characters including upper and lower case letters, numeric digits, and special characters
   • You can use the same password as your existing account
5. Review the Terms of Use and SAP Ariba Privacy Statement and select the box next to each indicating your acceptance
6. Click Skip review > Check box for I have read and I acknowledge the Cookie Notice and click Submit

The event should now appear for you.

You are receiving this error because the username you are attempting to use is associated with an ANID that does not match the ANID currently connected to your company's profile that was invited to the event, which indicates that your organization has more than one ANID.

With multiple usernames, a simple way to ensure you can easily access each will be to link your user IDs.
