Filter by Item Group

[Francisco_Buendia]

I finally made it!!!

frappe.ui.form.on("Quotation", "refresh", function(frm) {cur_frm.fields_dict['items'].grid.get_field('item_code').get_query = function(doc) {
        return {
            filters: [[
                'Item', 'item_group', '=', doc.tipo_de_orden
            ]]
        }
    };
});
