var grRequestedItem = new GlideRecord('sc_req_item');

grRequestedItem.addQuery('number', 'RITM0016916');

grRequestedItem.query();

while (grRequestedItem.next()) {

 gs.addInfoMessage('Variables for ' + grRequestedItem.getDisplayValue());

  for (var prop in grRequestedItem.variables) {

    if (grRequestedItem.variables.hasOwnProperty(prop) ){

     var variable =  grRequestedItem.variables[prop].getDisplayValue();

      gs.print(prop + ': ' + variable);

    }

  }

}

output:
