How can I get external number value to the incident field (REST)

[DIVI1]

Hi, 
I'm working on REST API integration and I've created form and also Business rule for "Create Incident" process,

but now I have to create also "update incident" process and here I have a problem. Cause I have a script and definitely something is not working properly... I've created new field in a incident form "u_isd_ticket" and now I want to get number value from another platform to this field. the target field is "correlation_number", waht do you think how to correct a script code?

(Other form value:
When  - async

checkbox UPDATE = true

and also condition for assignment group)

Hi @DIVI1 ,

Try below code 

(function executeRule(current, previous /*null when async*/ ) {

    var ticketcmdb = 'GFP 0020764392 000';
    var ticketcat = 'Human Resources Payroll';

    var r = new sn_ws.RESTMessageV2('NTT API Integration', 'NTT POST');
    r.setStringParameterNoEscape('u_description', current.description);
    r.setStringParameterNoEscape('u_short_description', current.short_description);
    r.setStringParameterNoEscape('u_state', current.state.getDisplayValue());
    r.setStringParameterNoEscape('u_priority', current.priority);
    r.setStringParameterNoEscape('u_system', ticketcmdb);
    r.setStringParameterNoEscape('u_category', ticketcat);
    r.setStringParameterNoEscape('u_number', current.number);
    r.setStringParameterNoEscape('u_comments', current.comments);
    r.setStringParameterNoEscape('u_work_notes', current.work_notes);
    r.setStringParameterNoEscape('u_assignment_group', 'SAP');
    r.setStringParameterNoEscape('u_correlation_number', current.isp_ticket);

    var response = r.execute();
    var responseBody = response.getBody();
    var statusocde = response.getStatusCode();
    var errormsg = response.getErrorMessage();

    gs.info("responseBody" + responseBody);

    var responseObj = JSON.parse(responseBody);
    gs.info("Correlation number check " + responseObj.correlation_number);
    current.u_isp_ticket = responseObj.correlation_number;
    current.work_notes = "information: Ticket successful created. Ticket number: " + responseObj.correlation_number;
    current.update();

})(current, previous);

Still if you are facing share the logs and check what values you are receiving

Now finally I've got a message in a work notes: 

But field is still empty, I wanted to implement here the correlation_Number value:

Hi @DIVI1 ,

can you check logs as well what values we are getting on those?

I just implemented this part of your script in a "create incident" Business rule except "Update incident" and it's working! 
Thank you so much! 🙂

*Instead of "Update incident" ^^
