R12 Making Screen Read Only

Hi,

We could make any screen query only in R11 version by adding a form parameter query_only=yes. such as any screen about vendor.

But in R12 most of that screens become an OAF page, So we can not convert its easy a stand alone, query only version.

Are there any parametric way to make that kind of R12 OAF based screen such as defining,enteirng vendor info screen etc, query only ?

If not, we try to make a profile value which assign a responsibility weather becoming query only or not.

Are there any suggestion to do that ?

Thx
