Parent Work Order for Manufacturing Process

Summary: We are losing visibility of the sub-assemblies that are part of our Finished Goods (also sub-assemblies of sub-assemblies). Once a finished good WO is created, the sub-assembly work orders are also created. I cannot find in any of the work execution tables where there is a link to the sub-assembly.

Example: We have multiple sub-assemblies that can be used in multiple finished goods. We lose visibility of which sub-assemblies are allotted to which finished goods, since there is not a link between the two work definitions. In the example attached, once we view the Work Order for the FG, our production lines are unable to match the Work Order for it's sub-assemblies.
