Different customer data per sales area
If a customer is served by two sales areas, I understand that we can maintaind different data per sales area.
I have a customer who is served by two sales areas and i need to maintain different tax classification for each.
Sales area 1 - 1000/10/12 , Tax classification 1
Sales area 2 - 1000/20/15 , Tax classification 2
However when i change the tax classification for one sales area, the same is updated for the other.
Is it not possible to maintain different tax classification for a customer for different sales areas?
Could some one answer this?
