The system treats co-/by-product records as standard work order records; however, there are differences. Co-/by-products do not have their own BOM and routing. The system creates a joint order set automatically when the co-product item references the base process BOM on the item master. This is part of the standard set up for joint order items. So, you can create a co-/by-product joint order set dynamically by creating an order from the base process or co-/by-product item.

When you create, the system immediately displays the complete co-/by-product joint order set.The default order due date of all orders in the co-/by-product joint order set are based on workbench current logic. The co-/by-product items must specify the BOM code of the base process item in Item Data Maintenance.

You can add an order to the joint set when you create the order on the workbench and use the same work order number of the joint set on the new order. The item on the new order must be an item not currently part of the joint product structure.
