Best way to plan prices, head-count etc...

Hi all,

I've been spending quite some time thinking about an appropiate way to implement the following requirement:

Planning quantities and also prices through different dimensions.

Standard behavior in BPS is that everything gets summed up. Let's say I plan my regional sales volumes (quantities, prices, amounts) and then switch to the national planning level. My regional prices would then SUM UP to an astronomically high national price (and not average or max etc.). BPS simply ignores the aggregation behavior flag of the InfoObject. So what to do?

Is there a best practice to plan with prices in BPS?

Many thanks in advance!
