Currently working Entra ID in Sailpoint ISC, I have created a custom transform for UPN and mailnickName, Few accounts got created in entra, few not. I found the issue, There are some spaces in lastname. Due to that account creation not happened its failed. I have created a username geerator for UPN and mailnick Name, also tried repalceall transform to remove space, Still didn’t work. Please find the attched provisioning plan for the identity.
