The import interface 'PuT supply from Visum' fails with an error message: 'The calendars in the source and target network are not compatible.'
The valid days of source and target version file do not match, e.g. the target version file uses no calendar, the source version file some annual or weekly calendar. Workaround: Equal this setting, e.g. choose in the source the option 'No calendar': Network -> Network settings -> Basis -> Calendar
