Rename unit or update code:
Go to Employees > Units. You'll receive a list of units with an edit icon (magnifying glass) next to them.
Update the unit's name and code in the unit's information and save the information. NOTE: make sure that the deleted units do not have the same name or code. First delete/change the information from the deleted unit, and only then add it to the active unit, so that there are no duplicate names or codes in the service.
To update a deleted unit you should restore the unit first - see Restoring a removed unit.
