For som Companies that sells items With large variances in price (both sales and cost price) the classifications in Operations (actually from at least AX 2009) can come out verry wrong.
If a Company sells sealings that has a cost price for 0,5 euro and also sells bigger items with cost over 100 Euro, operations will not care that the sealing might be more important and has a larger sale than the more costly item. The costly item will be given higher classification than the seal.
Turnover is the customer demand and should always be important for a Company. It indicates also how important that item is for the market.
Dynamics operations should add a New classification for Turnover.
