OPM Costing - Cost Allocation Factor

Dear All,

We have a specific scenario in the metal industry where in a production batch we are consuming cost of metal and conversion cost. The output of the batch is a finished product in metal terms and metal scrap. The metal cost and conversion cost has to be loaded on the finished product and the scrap, although a byproduct has to be valued only at metal cost (rate). The standard functionality in OPM has two options - i) keep FG item and scrap as co-products, in this case conversion cost will get loaded on scrap which we don't want ii) keep
