1. XML Access Rule:

The XML definition you provided for restricting partner access seems correct, but you might need to double-check a few things:

• Make sure the group hat_sales_updates.part_restrict_group is properly assigned to the intended users.
• Ensure that the field team_id exists in the res.partner model and is correctly populated.
  

2. Maximum Recursion Depth Issue:

The recursion error usually occurs because the _search method is being called repeatedly without an exit condition. This may be happening because your method is causing an infinite loop. The _search method might be invoking itself indirectly.

Here's a refined version of your _search method that should help avoid recursion:

class ResPartner(models.Model):
    _inherit = 'res.partner'

    @api.model
    def _search(self, args, offset=0, limit=None, order=None, access_rights_uid=None):
        # Avoid recursion by checking the environment
        if self.env.context.get('prevent_recursion', False):
            return super(ResPartner, self)._search(args, offset=offset, limit=limit, order=order,
                                                   access_rights_uid=access_rights_uid)

        if not self.env.user.has_group('hat_sales_updates.part_restrict_group'):
            args = [('team_id', '=', self.env.user.sale_team_id.id)] + args

            # Set a context key to prevent recursion
            ctx = dict(self.env.context, prevent_recursion=True)
            return super(ResPartner, self.with_context(ctx))._search(args, offset=offset, limit=limit, order=order,
                                                                    access_rights_uid=access_rights_uid)

        return super(ResPartner, self)._search(args, offset=offset, limit=limit, order=order, access_rights_uid=access_rights_uid)

The line self.env.context.get('prevent_recursion', False) checks if recursion prevention is already in place.

• self.with_context(ctx) sets a context variable prevent_recursion to avoid further recursion calls.
  

You might also need to update your access rules. Make sure you have a record rule like this:

    Partner restricted to sales team
    
    
    [('team_id', '=', user.sale_team_id.id)]

Try these adjustments, and restart your Odoo server to apply the changes.

Hi Asma,
Did you find any solution for it?

I think u should use xml ir.rule only

You need to add another record rule for hat_sales_updates.admin (if you have any) with domain_force 1=1 too this way will help Michell Admin can accessible
