Discrete Orders
The QAD EE legacy co-\by-product capabilities are only available for discrete work orders. The workbenches let you schedule both discrete and repetitive orders on a production line. This means that when you schedule with the workbenches, you leverage the co-/by- product functionality in a repetitive environment because the workbenches let you schedule discrete joint order sets on a production line.
If you use the workbenches for repetitive scheduling, but require co-/by-product scheduling functions, you should consider whether scheduling with discrete orders meets your requirements. When you consider this change, you should keep in mind these additional changes:
To backflush, you must use Work Order Receipt Backflush (16.12) and Work Order Operation Backflush (16.19) for backflushing instead of advanced repetitive Backflush Transaction (18.22.13).
There are costing differences between discrete and repetitive orders.
