A company procures different metals as raw material for production.
Metals include Copper, Brass, Silver.
Within Copper there are 3 grades: G1, G2 & G3
In Brass & Silver also there are 4 grades each.
If I want to get the report of price & quantity of Copper of grade G1 in Plant/storage Location, then how shall I define/classify the materials (in Material types, material groups etc) so that I get the desired report.
