Consuming On-Premise OData using XSJS in Multiple Cloud Connector Scenario

What is Multiple Cloud Connector Scenario ?

With new version release of SAP Cloud Connector , it is possible to connect different Backend system from Different Locations to one SAP Cloud Platform via multiple cloud connectors. Below Image helps to understand more.


I faced issue while connecting to the on-Premise systems due to the Location ID. Also couldn’t find access related issue in Cloud Connector.

In this blog i will technically help how to define the destination file and  setting the header parameter for Location in case of Multiple Cloud Connector scenario


Scenario : I want to consume an On-Premise OData service in SCP using XSJS based on a business requirement.

Note : We can use OData Provisioning in SCP for Connectivity to On-Premise OData Service.


Lets define Destination file : gateway.xshttpdest

host = "ecc.virtual.address";  // Virtual Host defined on Cloud Connector
port = 5000;                   // Virtual Port defined on Cloud connector
pathPrefix = "/sap/opu/odata/sap/EHS_INC_REPORTINCIDENT_SRV/"; // OData Service
useProxy = true;    // Its should be true , as we re using On-Premise system 
proxyHost = "localhost";  //connects, via a Cloud Connector tunnel, 
                         //to on-premise services and resources
proxyPort = 20003;     // Proxy Port
authType = basic;     // Authentication Type is Basic Authentication
useSSL = false;
timeout = 30000;


Maintain the Authentication details in XS ADMIN Tool.

The Basic Authentication details , it should be the User/Password of the On-Prem ECC System . 

After any changes in .xshttpdest file , need to update the User details in XS Admin Tool.Because its gets refresh after any changes .


Create a XSJS file to consume the service : GetLocation.xsjs

var destination_package = "Test_XSJS.OdataFromXSJS";     //
var destination_name = "gateway";          //e.g. demo
var dest = $.net.http.readDestination(destination_package, destination_name);
var client = new $.net.http.Client();
var response = client.getResponse();  
try {      

var req = new $.web.WebRequest($.net.http.GET, "Locations?$format=json");//Entity Set 
req.headers.set("SAP-Connectivity-SCC-Location_ID", "Bangalore");
// This is mandatory .Else the Call from XSJS fails to find the exact 
//cloud Cloud Connector Instance which is mapped to the Backend ECC System
req.headers.set("X-CSRF-Token", "CSRF");
client.request(req, dest);

$.response.contentType = "application/json";
$.response.status = $.net.http.OK;

 catch (e) 
$.response.contentType = "text/plain";


Activate the project and Run the XSJS . It should get the results .


Finally !! We have consumed an On-Prem OData Service in a Multiple Cloud Connector Scenario.

      Hi, Aisurya Puhan.

      When I run the xsjs file, HTML text is displayed on the screen with the following note: Your browser does not support JavaScript or it is turned off. Press the button to proceed.

      I am getting the error "500 Internal server error" while trying to run the XSJS application.

      Are you familiar with this error?

      Hi Aisurya,


      Here is the code:


      $.trace.error("Can you see me?");
      var custnum = $.request.body.asString();
      var essai = custnum.toString().replace("\r", "").replace("\n", "").replace("\t", "");
      essai = JSON.parse(essai);
      var Prioritytickt = essai.Prioritytickt;

      try {
      $.response.contentType = "text/html";
      var dest = $.net.http.readDestination("", "Destination");
      var client = new $.net.http.Client();
      var req = new $.web.WebRequest($.net.http.GET, "MessageResultSet?$format=json"); //Entity Set
      req.headers.set("SAP-Connectivity-SCC-Location_ID", "PSB");
      client.request(req, dest);
      //var response = client.getResponse();
      var response = client.getResponse().body.asString();

      //$.response.contentType = "application/json";
      var result = response.body.asString();
      var jsonResult = JSON.parse(result);
      var chatbotResponse;

      if (jsonResult.d.results.length > 0) {

      if (Prioritytickt === "2") {
      chatbotResponse = "Here are the high priority tickets ";
      if (Prioritytickt === "3") {
      chatbotResponse = "Here are the medium priority tickets ";
      if (Prioritytickt === "4") {
      chatbotResponse = "Here are the low priority tickets ";
      if (Prioritytickt === "All") {
      chatbotResponse = "List of all the tickets ";

      if (Prioritytickt !== "All") {
      var ticketdetails = jsonResult.d.results.filter(function(hero) {
      return hero.Priority === Prioritytickt;
      for (var i = 0; i < ticketdetails.length; i++) {

      chatbotResponse += ticketdetails[i].ObjectId;
      if (i < ticketdetails.length - 1) {
      chatbotResponse += ", ";

      } else {
      for (var i = 0; i < jsonResult.d.results.length; i++) {

      chatbotResponse += jsonResult.d.results[i].ObjectId;
      if (i < jsonResult.d.results.length - 1) {
      chatbotResponse += ", ";


      var output = {
      replies: [{
      type: 'text',
      content: chatbotResponse

      conversation: {
      memory: chatbotResponse
      var body = JSON.stringify(output);
      $.response.contentType = 'application/json';
      $.response.status = $.net.http.OK;

      } catch (e) {
      $.response.contentType = "text/plain";



      I am getting error from line: var custnum = $.request.body.asString();


      Any ideas?
