In 7.5 SP3, does anyone know if you can block out a partial day instead of a whole day in a Resource Calendar? Our default right now is FTE's for Resource Pools and Staffing Profiles. I don't believe changing it to Hours as a default will change this, but if someone thinks it's worth a shot. I will try it.
Unfortunately this is a missing functionality. We developed an interface from Lotus Notes to PPM to fill the resource calendars automatically and there is no way to, say, take half a day off. But I am sure there are enhancement requests regarding this issue.
