Try below code:
frappe.ui.form.on(“Product Bundle Item”, {
qty: function(frm,cdt, cdn){
calculate_total(frm, cdt, cdn);
},
rate: function(frm, cdt, cdn){
calculate_total(frm, cdt, cdn);
}
});
var calculate_total = function(frm, cdt, cdn) {
var d = locals[cdt][cdn];
frappe.model.set_value(cdt, cdn, “total_rate”, flt(d.qty * d.rate));
}
