We are currently on PPM v9.32. We wanted to understand the impact of newly configuring holidays on the default region calendar which has been in use for a few years now. What will be the possible impacts on the existing forecast calculations and utilizations.
If the resources are using regional calendards then, yes, certainly there will be impact on the capacity of the resources. If they are assigned to a week where there is a public holiday, then it will be shown as over-allocation. The capacity will be reduced as well.
I dont think there will be any impact on the forecast as such.
When creating holidays in the existing default Calendars used by all the resources.
Example for existing position: if PM forecasts 1 FTE,
before the change = 1.00 FTE
after the change = 1.05 FTE
if PM forecast by hours:
before the change = 152 hours
after the change = 152 hours
The new allocation (of the resources) are also based on the newly updated calendar. If the resources were allocated during the new calendar holiday time, they would show as over allocated. or if you mark any holidays as working day, it would show as under allocation for the committed resources
