to Lock the rfx response when rfx is locked

Hi all,

i had a requirement to lock the rfx when a extension field hold is selected.

iam able to lock rfx. but couldnt lock rfx response.

like the vendor login to his view and when he sees the rfx for response it should be locked mode

beacause the rfx was locked.

i tried but couldnt do it.

if any one have any idea

request you to share it .

thanks
