Hi MM SRM,
If you want to use other characteristics for product and location than 9AMATNR and
9ALOCNO, you must specify these characteristics in the master planning object
In general you should use the two SAP characteristics as the basis for the new
The main reason for changing these characteristics is to be able to use navigational
attributes in Demand Planning without causing problems afterwards in SNP (SNP does
not support navigational attributes)

Another advantage is that if you assign the product and location characteristics in planning object structure, the product and location description from the product location master in APO is pulled into the planning book as description for the product and location characteristics. Otherwise, you will upload the descriptions for the product and locaiton characteristics.
