We need help on creating an import to overwrite EE#'s without creating new accounts. I have tried to use Employee as the Entity with Update and merge as the operation. We thought it was a simple script where we overwrite the EE#'s while using either the User Name or email address as the look up value. Would anyone have a working import script on overwriting something like EE#'s that they could share with us? I have uploaded the update and merge scripts I have tried to use and it does not work.
