Hi @raj765_32 

You need client UI Action for this:

In UI Action :

Client checkbox should be true

Action name : give any name here,this will be used in gsftsubmit in the script.

onclick:onClick();

code://modify field names accordingly

function onClick() {
    var usrResponse = confirm(getMessage("Pease confirm that you want to cancel "));
    if (usrResponse == true)
        gsftSubmit(null, g_form.getFormElement(), 'cancel_case'); //Add the action name here
    else
        return false;
}


if (typeof window == 'undefined')
    cancelCase();

function cancelCase() {
  var gr = new GlideRecord('xyz');
    gr.addQuery('purchase_order', current.sys_id);
    gr.query();
    while (gr.next()) {
        gr.status = 'canceled';
        gr.update();

    }    action.setRedirectURL(current);
}
