Why do we need to plan promotions at the lowest level of aggregation

[Former Member]

Hi,

The documentation says that we need to plan the promotions at the lowest level of aggregation i.e., the material level. Why? Is there a specific reason for this? Can we plan at other levels of aggregation as well? What happens if we plan at higher level;s of aggregation?

Thanks.

I think it is possible to do it in an aggregated level however you need to define your distribution rules in order to get the desired result, you need also to consider that if distribution rules changes and the value after promotional planning returns the same value, it is possible that detailed level are not realigned to the new distribution rule (e.g. regarding another ratio).

Maybe this is one of several causes.
