Diagnosis
With rent adjustments according to Swiss law, the adjustment date iscalculated from the entered "valid from" date and the noticearrangement in the rental agreement. In this case, only the rental unitwas adjusted (either a rental agreement was not defined or only rentalunits were to be adjusted).
Since the adjustment date cannot be calculated here, the "next standardnotice date" is used. However, this was not specified on the initialscreen.

System Response
The adjustment cannot be carried out.
