FAQ: Can you bulk populate the 'Assessor number' field for EPAPro in Aptem via CSV upload?
Admin/Employer accounts cannot be updated via CSV upload, so this will need to be done manually.
However, if there are lots of learners with the same Case Owner, it is enough to update only the Case Owner's mobile. All valid user records in EPAPro will be updated automatically. However, this is valid only if the new mobile number is deemed valid by EPAPro, and of there are no other errors for the learner.
