Production Planning & Subassembly
if you need Production Planning Tool to consider raw-materials required for the manufacturing of sub-assembly items selected in the BOM, please check following instructions to achieve the same.
Production Planning Tool has field called "Use Multi-Level BOM", checking which will consider raw-material of sub-assemblies as well in the material planning. If this field is not checked, then it will consider sub-assembly as an item, and won't consider raw-material required for the manufacturing of that sub-assembly.
Use Multi-Level BOM field is also there in the Work Order and Stock Entry. If checked, raw-materials of sub-assembly item will be consumed in the manufacturing process, and not the sub-assembly item itself.
