The promotion key figure has to be the lowest level of detail, which means the KF has to be the lowest in the hierarchy. This means, I can only assign promotions at the lowest level?
For example, a product called DOW white color soaps and a group level called DOW soaps. So as per the promotion planning, I can only set promotions at the DOW white color soaps and not at the group level of DOW soaps? is that true? What if I have a case that I have to specify a promotion at group.
