I've use MD02 then MD04 to calculate materials consumption and list out the list. Acutally, our business is trading industry, So every parts is purchase externally. For single material, use md02 and md04 it is OK, because I just want to list out the material and convert PR to PO if needs, but for BOM materials, if put the mother materials in MD02 to calculate the consumption and then list out at MD04, it can be convert PR to PO, but it only for mother material only, I would like to know can I have a list, just put the mother material, the child component will be listed out also. and then convert to PO from PR. Thanks!
