Thank you @linto

can you provide me with screen shoot how to do this

Hi, you can achieve this simply by creating a compute field in 'crm.team' model and use this field in the sales team kanban view to filter the teams so that a user can see only his teami.e,in your .py file,

    _inherit = 'crm.team' 
    current_team_status = fields.Boolean(string="current user", compute='get_team') 
    @api.multi def get_team(self):
          u_id = self.env['res.users'].browse(self._uid) 
          for rec in self:
             rec.current_team_status = False 
             if u_id.has_group('base.group_sale_salesman_all_leads') and u_id.has_group( 'base.group_sale_salesman') and u_id.has_group('base.group_sale_manager'):
                    for rec in self:
                        rec.current_team_status = True 
             elif u_id.has_group('base.group_sale_salesman_all_leads') and u_id.has_group('base.group_sale_salesman'):
                teams = self.search(['|', ('parent_team.user_id.id', '=', u_id.id), ('user_id.id', '=', u_id.id)])
                for team in teams:
                    team.current_team_status = True 
            elif u_id.has_group('base.group_sale_salesman'):
                team = self.browse([u_id.sale_team_id.id])
                team.current_team_status = True

and in your xml file, 

     <record model="ir.ui.view" id="sales_team_kanban_view_in_crm_bs"> 
        <field name="name">crm.team.kanban</field> 
        <field name="model">crm.team</field> 
        <field name="inherit_id" ref="sales_team.crm_team_salesteams_view_kanban"/> 
        <field name="arch" type="xml"> 
        <xpath expr="//sales_team_dashboard/templates/t/div[1]" position="inside">
             <field name="current_team_status" invisible="1"/> 
        </xpath> 
        <xpath expr="//sales_team_dashboard/templates/t/div[1]" position="attributes"> 
            <attribute name="attrs">{'invisible':[('current_team_status', '!=', True)]}</attribute>
         </xpath> 
       </field>
     </record>

Now the admin can see all the teams in dashboard and the user can only see his team. 

Hope this will help

thank you
