Open a system form using form Unique ID

Hi All,

I have created a user defined form using screen painter, to which i have added a button. What id like to do is that on click event of the button i would like to open a system form which does not have a menuid (egs : 3007 is unique id of freight info, and it does not have menuid)

So is there anyway to open a system form that does not have an Menuid .

Thanx in advance for any replies......
