Issue

When trying to register for SAP Ariba Sourcing, the system displays the following error:

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

Resolution

There are two solutions to this issue:

  1. Create an alternate username by clicking Sign Up through the event invitation. Your new username will need to be different than any existing registered username. If not, you will face an user already exists error message.
  2. Contact SAP Ariba Customer and have them unlink the existing accounts if possible. 
Cause

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 Ariba Network username to a one user profile for each buyer.
