Hi Jaydeep,
I asked you to try from SDK and not from adapt 
.
Through SDK you have an option of implementing the UI switches where in the developed UI switch you can customize the SAP screen (Hide/Un Hide some fields,buttons,links etc.,) and assign the same to a Business Role, this business role will be assigned to a user where the customized screen will be viewed by those who logged in.
Please try this. In the SDK PDF you have a detailed session explained to implement this.
Regards
Hanu
