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)

[DIVI1]

I've got confirmation of sending and also receiving ticket in an external platform in a system logs also I can see there a value of correlation_number which is necessary for me to implement it to isd_ticket field. 

[DIVI1]

But these logs are form "create incident" form created by another business rule.

Hi @DIVI1 ,

Don't share only screenshot. share script that you are working that will help a lot to provide solution.

Hope you will share script as well in future.

on your script No need to use GlideRecord because business rule is on incident table. you can use current object to update data.

Refer below code and replace with your fieldnames. 

current.u_isd_tiket= responseObj.correlation_number;
current.work_notes="NTT infomation: Ticket successful created. Ticket Number: "+responceObj.correlation_number;
current.update();

Thanks it's not working yet.
I've got logs like:

responseBody{"action":"AddInfoResponse","PersonMaps":{"item":{"PersonId":"0000036641","PersonIdExt":"0000036641"}}}

after creating incident I reveiving logs like:

responseBody{"action":"ProcessIncidentResponse","PersonMaps":{"item":{"PersonId":"0000036641","PersonIdExt":"0000036641"}},"correlation_number":"9000809481"}

And the full script of Update incident:

(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);

(function(response) {
var responseObj = JSON.parse(response);
current.u_isp_ticket = responseObj.correlation_number;
current.work_notes = "information: Ticket successful created. Ticket number: " + responseObj.correlation_number;
current.update();
});
}
})(current, previous);
