Introduction
Within QAD EA, you can use a special set of features for managing processes that create more than one product. Such products are referred to as joint products, and each joint product is made up of co-/by-products. Processes that create only one product are supported by regular bills of material (BOM) and formulas.
Co-product/by-product features support a variety of manufacturing operations, including batch processing, sorting, molding, support for MRP, work orders, shop floor control, and costing, as well as tools for setting up items, structures, and routings.
You can schedule orders for co- or by-products within the workbenches. You should understand concepts before you begin working with these product types.
