Hi,
I am not sure what you mean by "on order stock qty" (rejected materials), but if you are using MRP type PD it will look at all documents and items that will affect stock (POs, Planned orders, requisitions, sales orders, production orders, PM orders etc. etc.).
This is not configurable or changeable because the logic of PD is "Full planning" or "Plan Deterministic" (determining everything that affects stock).
You have some minor control over things such as "stock in transafer" and "blocked stock", you can decide if MRP should ignore or include these. But if you use PD then all of the above will be considered.
You can use other MRP types such as reorder point planning and this ignores all of the above and just maintains the stock levels above or equal to the reorder point. (although you can even configure reorder point MRP to take orders etc. into consideration).
So unless you switch to reorder point planning or forecast planning you will find that the above types of document / orders will be considered by MRP.
