Hi Jithin

It is a good example

https://www.odoo.com/apps/modules/9.0/openeducat_core/

https://www.odoo.com/apps/modules/9.0/openeducat_assignment/

Then open /openeducat_assignment/dashboard/assignment_faculty_dashboard.xml

<record model="ir.ui.view" id="assignment_faculty_dashboard_form_view">
     <field name="name">board.faculty.form</field> 
     <field name="model">board.board</field>
     <field name="inherit_id" ref="openeducat_core.board_faculty_form" /> 
        <field name="arch" type="xml"> 
            <xpath expr="//board" position="inside">
                 <column> 
                    <action name="%(act_op_faculty_assignment)d" string="Assignments to Approve" />
                 </column> 
            </xpath> 
        </field>
 </record>
