Hi everybody

I code :

class input_import_excel(osv.osv):
    _name="input.import.excel"

    _columns={
       
        'properties': fields.many2many('cvs.quotations.report', 'report_id_rel',"id_excel","id_report",'Properties'),
      
    }  

View :

<record id="view_cvs_quotations_input_import_excel_form" model="ir.ui.view">
            <field name="name">input.import.excel.form</field>
            <field name="model">input.import.excel</field>
            <field name="type">form</field>
            <field name="arch" type="xml">
                <form string="Danh Sách" version="7.0">
                    <field string="Vật Tư" name="properties">

                           <tree delete="false" create="false" name="Kiểm Kho">

                            <field name="name" ></field>
                             <field name="dvt"></field>
                            <field name="tongdutoan" ></field>
                            <field name="tongxuat" ></field>
                            <field name="chenhlech" ></field>

                             <field name="tongtien" ></field>

                        </tree>
                    </field>
                    </group>

                </form>
            </field>
        </record>

I want to remove the add and delete buttons in many2may, I used the delete = 'false' but it did not work

Can you help me ?
