How to send the ritm variable value to 3rd party

[Nisha B]

Hello All,
I have build soap message to send the RITM information to 3rd party.
This soap message is calling through business rule but when I am trying to send the variable value , it is giving me undefined .
I just want to send only the 3 variables from that not all variable and code is like-

req.setStringParameter('request.Operation','current.variables.request_type');

req.setStringParameter('request.SecurityID','current.variables.owned_by_create.user_name');

req.setStringParameter('request.Description','current.variables.description_create');

but above is giving undefined .Please suggest .

I am using below code in business rule

 var grVar = new GlideRecord('sc_item_option_mtom');

   grVar.addQuery("request_item",current.sys_id);

   grVar.query();

   while (grVar.next()){

         var fieldName = grVar.sc_item_option.item_option_new.name.toString();

         var val = grVar.sc_item_option.value.toString();

 gs.log("Update Option value Nisha   "+fieldName +" "+ val);

}

but this is giving all variables I just need 3 variable and that need to be send on soap message.

I am using below script -

 var grVar = new GlideRecord('sc_item_option_mtom');

   grVar.addQuery("request_item",current.sys_id);

grVar.query();

   while (grVar.next()){

         var requestType = grVar.sc_item_option.item_option_new.name.toString();

         var val = grVar.sc_item_option.value.toString();

        gs.log("Update Option value"+requestType +" "+ val);

   }

I am getting all the variables , I just need 3 variable among that for eg A1, A2, A3 and only this 3 variable I need to send.
