SAP SuccessFactors Learning Management System (LMS)

Reproducing the Issue

  3. Click Save button
  4. Receive error "The e-mail address {{0}} must be unique."


The e-mail address was used for a Plateau Talent Gateway user.

A Plateau Talent Gateway user should have unique e-mail address and therefore the same e-mail cannot be used in another user record again.


  1. Navigate to the user record that faced the "The e-mail address {{0}} must be unique." error.
  2. Click View All
  3. Find the Plateau Talent Gateway Access field
