I doubt it could be a proxy issue. Anyway, Can you share screenshots of the HANA Cloud connector settings,Mapping virtual system to internal system and Add resource?

Perform the following in chrome: Tools>Developer Tools>Console

Reproduce the same issue. What error do you see?

You can check this guide as well.

Hi Jitendra,

Below is the screen shot reproduced for the issue:

Error:

GET https://webide-trial.dispatcher.hanatrial.ondemand.com/destinations/ECC/sap/opu/odata/IWFND/CATALOGS... 503 (Service Unavailable)

Uncaught (in promise) Object {message: "HTTP request failed", request: Object, response: Object, statusCode: 503, statusText: "Service Unavailable"…}

[Jitendra_Kansal]

I assume you can access the same Odata service in a browser.

can you also share screenshots for "System Mapping" and list of resources you have added in HANA Cloud Connector as mentioned in the guide in my previous reply and also share the screenshot for the DESTINATION created in cockpit?

HI,

Is this blog helpful?

If not please attach screen shots of your configured destination in your cockpit and HCC (you can hide the internal info such as host and port)

I think below screenshots will give you more idea.

Hi Michal,

I am getting "Cannot open tunnel with id account:///<USER ID>trial" error. Can you suggest any ideas to resolve this

[Jitendra_Kansal]

Can you cross check if SID of back-end system is ECC (as you have mentioned it for WebIDESystem property)?

Can you also modify value for WebIDEUsage?

WebIDEUsage: odata_abap,dev_abap,ui5_execute_abap

Regards,

JK

When you get the "cannot open tunnel" error it means your cloud connector is either down or isn't configured properly. Can you verify your cloud connector is connected?

[Former Member]

When I open Start SAP HANA Cloud Connector. I am geeting the below message.

"Could not open Service Manager".

While checking in Connector State, the status is connected.

SID name is correct. I have modified WebIDEUsage, but still I face the issue.

Hi,

Try checking your PATH variable, which you can find in environment variables.

You might need to add SAP-JVM bin path to this variable.

I have done it already. Yet the issue is not resolved.

Hi Rahael,

"Could not open Service Manager" is a standard Windows error message that comes when you try to open the Windows Service Manager with a non-administrator user. If you want to start the SCC as a Service, you need to right-click on the start icon and then choose "Run as Administrator".

However, your SCC already seems to be running. Did you start it manually via go.bat?

In any case, your original problem seems to be quite simple: in your destination settings you have specified the URL "http://....", while your cloud app makes a request using "https://..."

Switch your destination from http to https.

In the SCC settings, the "virtual host" should be the same that the cloud app is using, so in this case:
Virtual host = webide-trial.dispatcher.hanatrial.ondemand.com
Virtual port = 443

The internal host needs to be the real hostname or IP adress of your ECC system and the port on which it is listening.

When in doubt, just turn on the Audit Log on SCC and you will see, what kind of request the cloud side is sending, and to what the SCC is forwarding it. (Or an error, if no system mapping exists for the host requested by the cloud side.)

Hi Ulrich,

I tried your steps, yet the issue is not resolved.

Could you plz clarify me, virtal host has to be mentioned without user id (webide-trial.dispatcher.hanatrial.ondemand.com) or with user id (webide-PXXXXXXXXXXtrial.dispatcher.hanatrial.ondemand.com).

Plz let me know if any thing has to be done.

Hi Rheema,

the virtual host is not the address of your cloud application on hanatrial, but the host you invented in the destination you use in for reaching the OnPremise network. You have defined it in the cloud cockpit destinations section. Use the host and port information from this destination.

Best regards,

Markus

Hi Rheema,

yes, in your audit log it looks like you are using a host and port of "ttpl001.truspeq.com:8443" in your destination on Cloud side. So the virtual host and port in the SCC also need to be "ttpl001.truspeq.com:8443". Please also see our documentation at SAP HANA Cloud Platform where this is documented in detail.

Basically your virtual host and port can be "anything" -- even "mickey-mouse"...    Important is only that it matches exactly the host and port value that is specified in the HTTP destination on Cloud side!

try using cloud connector.The SAP HANA Cloud connector is an optional on-premise component that is needed to integrate on-demand applications with customer backend services.

Hi Rajeesh,

I have configured the SAP HANA Cloud Connector.

I have query regarding System Mapping: Which url has to be specified in Virtual host and Internal host?
