The scenario is as below:
I have a material A. Its BOM has a co-product B. I have ticked the co-product indicators in mat. masters of both A and B. B has negative quantity in the BOM of A and also, the tick is made in the BOM.
My first question is: whether B is to be maintained as HALB or as ROH? If as HALB, then price control would be S and how will costing take place? If as ROH, then price control would be V, and how will costing take place?
Second qustion is: do i also have to maintain BOM and routing for co-product B?
Third question is: as of now, i have not maintained any BOM or routing for the co product. But, when i tried to take a costing run (CK11N ) for the co product B, then it showed the header material (A) under quantity structure. Why is it taking that material for the costing?
Kindly provide some insights.
You have to maintain the co-products as HALB or FERT, it cannot be ROH as generally ROH is a procured materail, and for that materail type default we dont use Work scheduling view and Sales views which are necessary for Production/Sales.
It depends upon how you want to execute production, say for example you want to excute plan based on both the products, then yes it has to be maintained. There can also be an option that Product B has to be produced separately but product A does not come as Co-Product here.
Since you have used Product A in the apportinment structure of the Joint production tab, system first looks for a suitable Quantity structure for Product A, if it does not find then it looks for the co-product and takes data from it.
Hope I was able to give some insights,
