It's true...SPS5 has changed a big deal...however, you don't need to worry about private attributes and measures...when you select the fields, the ones that can be calculated are going to behave automatically as measures, so there's no need to worry about them...just select all the fields you need and you shouldn't have any problem at all with BO or Excel.
Just to make things more clear to you...private attributes are just the fields that you use to join the tables...so no big deal about them...they will show up as columns with an icon next to them...
