@dheeru_1994Remove field you want to pass static value from field map and try below code in On After. It will work.

    var gr = new GlideRecord('cmn_location');

    gr.addQuery('uniqueValueoftarget', source.fieldtomapwithuniquevalue);

    gr.query();

    if (gr.next()) {

        gr.name = 'dfghjk';

        gr.update();

    }
