User Exit For Unreleased the PO

Hello,

I develop code in Exit to re-release  when getting change in quantity or Net price of PO .

it is working well but problem is that when user change delivery date it does not ask for release that is correct , but

release strategy tab disappears and we can do MIGO for this PO , when we want to print preview it gives a warning with Draft PO and

It should be show PO only not Draft PO . So please let me know if somebody have any solution for this .

Thanks
