ServiceNow to ServiceNow Integration using REST API and PUT method with Business Rule

[Hussain212]

In  (BR), I am attempting to update an incident in Instance A so that it is dynamically updated in Instance B. However, the correlation_id field is empty in both instances. I tried assigning the number field from Instance A to the correlation_id field in Instance B, and i do not want to use sys_id , since they are unique in both instances , but the update did not work.

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

    // Add your code here

    var incidentNumber = current.getDisplayValue('number');

    try {

        var r = new sn_ws.RESTMessageV2('Integration with dev278218', 'PUT a record');

        r.setEndpoint('https://dev278218.service-now.com/api/now/table/incident/' +incidentNumber);

        

        var body = {

            "short_description": current.getDisplayValue('short_description'),

            "caller_id": current.getDisplayValue('caller_id'),

            "correlation_id": current.getDisplayValue('number')

        };

        r.setRequestBody(JSON.stringify(body));

        //override authentication profile 

        //authentication type ='basic'/ 'oauth2'

        //r.setAuthenticationProfile(authentication type, profile name);

        //set a MID server name if one wants to run the message on MID

        //r.setMIDServer('MY_MID_SERVER');

        //if the message is configured to communicate through ECC queue, either

        //by setting a MID server or calling executeAsync, one needs to set skip_sensor

        //to true. Otherwise, one may get an intermittent error that the response body is null

        //r.setEccParameter('skip_sensor', true);

        var response = r.execute();

        var responseBody = response.getBody();

        var httpStatus = response.getStatusCode();

    } catch (ex) {

        var message = ex.message;

    }

})(current, previous);
