Christian, In essence the basic manufacturing process for producing an end product is the executing of a happy flow. When registering a new production run of e.g. 1000 washers it is the intention to register (as output of that production run) 1000 washers into inventory.
With predefined inputs (components, production resources like machines and workers) the defined output is generated. This is based on the BoM (the what) and the associated production schema (the how). Deviations of the happy flow leads to a diminished quality of the end product (not only when assessing the end product with regards to its acceptance parameters, but also when taking the cost of the product into consideration). Yes, the average cost of quality inspection and rework can be incorporated into the standard cost price. But these are based on statistics. The actual cost of the real inspection and rework on the (intermediate) product of a production run can deviate enormously from the standard calculation. With current functionality in the manufacturing component only the happy flow is addressed, with only a few predefined deviations. These deviations are also predefined, namely the registration of by and waste products and rejected end products. Now, back to your 'rework' scenario. Executing this scenario is hardly a happy flow. The amount of effort in this is difficult to define up front, and the output can be vary from scenario to scenario. So this is difficult to define in a BoM and related production schema. For that you can add tasks, components and resources to a production before confirmation. Moreover, given the variance of tasks, components and resources applicable from rework to rework you could regard it (in a way) as product development or (re-)engineering. But definitely not manufacturing.
