restrict migo if source inspection is opened or rejected

Hi Experts,

to restrict migo if source inspection is opened or rejected i have followed these steps.

Go to Q-info record (QI02) for that particular material, vendor and Plant combination.

1.Use Inspection Type 0101 for source inspection.

2.Number of days ahead of lot to be created.

3.Control key contains the control on GR in the QM view of MM.

In the spro >QM >QM in Procurement-->Define Control Key and assign it to MM.

We can define here under Source Inspection Control that in case of GR for rejection-->GR not allowed.

This will not prevent MIGO if in case Source Inspection Lot is rejected or opened.

please guide me if any thing is missing,

regards,
