Hi Community!

I have a question concerning work on public holiday. The set up is as it follows: 

If an employee works on public holiday, normally he doesn’t get any increments. The time is shown in the Time Card Day Result, but nothing happens. 
If the supervisor confirms the work on public holiday, an increment is added. Therefore the Day Type has to be changed into a Day Type with increments. 

But it seems, that the system has a problem with calculating a Deviation Day on days that are already substituted: 

Am I right with my assumtion that Substitute Days cannot be overridden with Deviation Days?

Best Regards,
