When trying to register for SAP Ariba Sourcing and access a sourcing event, the system displays the following error:

The username and password entered has already merged to another Ariba Sourcing user account.

Your buyer created a duplicate user profile for you in their company's supplier database. The system stops you from signing in because you can only connect your SAP Business Network username to one user profile for each buyer.

Depending on how you would like to proceed, there are two solutions to this issue:

1. Create an alternate username by clicking Sign Up in the event invitation. Your new username will need to be different than any existing registered username. If not, you will receive a user already exists error message. Keep in mind that if you choose this solution, you will have two separate accounts.
2. If you don't want to create a new account, contact your buyer and have them invite your existing account.

If you followed these steps and still need assistance, please contact SAP Support.
