Hello Prabhu

Try to do it within .py ,it will work always, but is there any specific purpose to apply in .xml ?

Thanks !

Yes, Mr. Dipak Shah. I have two forms of the parent class, when I add the domain in python it will apply to all forms. So, I need a domain for one form.

Okay . What if you are manipulate the domain using def fields_view_get method where you can check the specific form and and alter the domain as you want. :)
