Customer Master - Help in Personalization

Dear All,

    I am not able to find OAF community, so posting this in Receivables community. I have 2 requirements.

1)

I want to default the Account Description field with a 3 digit company code. And make that field to read only and while pressing the 'Go' button, results should be based on that defaulted Account Description.

I did that using personalization by setting the initial value to company code and setting the read only attribute to 'True'. But after doing that, I am not able to search with Account Description, which usually works. Once the field is made read only, I guess its overriding the search feature with that field. How to meet my requirement?
