If you are unable to approve RPTU accounts from your own Organization Unit (OU) on the RPTU account management page https://accounts.rptu.de, we will need a power of attorney from your cost center manager. You can find this here: https://rz.rptu.de/fileadmin/rhrk/account/Antr%C3%A4ge/Vollmacht.pdf (german only)
Please fill it out and send it by (house) mail to the RHRZ, located on the Campus in Kaiserslautern.
Once your power of attorney is approved, you can approve newly requested RPTU accounts within your OU.
