Discontinued parts - how include fixed receipts??

Question

In the MRP 4 view , we can set Discontinuation indicator for one material ,and defined the follow-up material.
And the system will transfers the dependent requirements in materials planning to the follow-up material if they are no longer covered by warehouse stocks.
In standard SAP system , When discontinuing parts, the system does not include fixed receipts such as order proposals or production orders if they are after the effective-out date. The system issues the "Please cancel and Receipt" after effective-out date exception messages in Stock/Requirement List  (MD04 View)
But we now indeed need the system to include fixed receipts,that is affter the last fixed receipt ,the discontimuting parts begin to take effect!
How to do this? How discontinuing parts include fixed receipts??
Thaks for any replay!

Hi Fei Liu,
The thing is rather simple; the idea with discontinuation is that from a certain date on we don't want to procure material A anymore, but B instead. Nevertheless, if there's any stock left from A I want to use it first.
In this situation, if somebody manually creates a fixed procurement element, like purchase or production order, the system will only create an exeption message for the planner, since by the normal course of the process this should not have happened.
If you have this situation happening a lot, the question is then if you're using the right functionality for your business case.
