Hi,
What time zone do you use to display on planning book? You need to first check /sapapo/mvm whether you've set local time zone for SNP. If yes, check time zone of the location.
Then check the time zone of the time series calendar (in /sapapo/calendar) you assigned to the destination location as receiving calendar. It should be the same as the time zone you're using for planning book.
If these are all OK, try to regenerate the time series calendar once.
Best Regards,
Ada
