Due to software updates of the HIS procedures and the databases at the University Service Center (HSZ), many important administrative procedures will unfortunately not be available from Wednesday 15.10. until Friday 17.10.2025.
Also affected are some self-service services.

The following services are affected:

• the IReMo environment (factual applications)
• HISISY (factual area)
• HIS-FSV, HIS-SVA, HIS-COB
• the self-service functions for employees (among other things the electronic
  leave card, the online time recording terminal and the time recording
  time recording web frontend):

For time recording, this means that no times can be booked during these days,
but you can book the times later.
