Dear Raghav
and what, if data is not changed on attribute but on root characteristic level? If a combination of root characteristics is not valid any more but shall be replaced with all it's historical and planning data from the old combination to the new combination?
( For those of us that come from APO: In Demand Planning, there was (is) a functionality called "Realignment" in which you could re-align one combination to a new combination by creating the new combination automatically and deleting the old one. )
If there will not be such a functionality, that would lead to the conclusion you would always need to model on the very lowest level of detail, which in most cases would be on customer and product number level plus sales area data and plants
Thanks
