SAP Analytics Cloud Live Connection


Live Connections

We can connect SAP Analytics Cloud to a multitude of data sources. The focus of this blog is on Live Connections to SAP HANA (Direct Path | CORS).

Direct (CORS) is the recommend approach over PATH (reverse proxy), cf. SAP Analytics Cloud – Live connections to on-premise data systems (CORS recommended)


In this series, we cover a live connection to SAP HANA using the Information Access (InA) Service. This service is exposed by SAP HANA XS (classic) and requires the following configuration before the connection can be established.

  1. Configure a public URL for the XS server. By default, XS is only accessible internally.
  2. Certify the public URL. By default, the XS server (Web Dispatcher) uses only self-signed certificates.
  3. Grant the INA_ROLE to a user. By default, no user has this role granted.
  4. Enable and confgiure external access to the InA service. By default, CORS (Cross Origin Resource Sharing) is disabled.
  5. Modify the session server timeout for the XS server. By default, the session times out in 90 seconds.

Create Live Connection

Creating a Live Connection to a SAP HANA system on SAP Analytics Cloud is a simple task for the business user once all the prerequisites have been met. We need to provide the public URL for the system, the HTTPS port, and for basic authentication a user name and password, e.g.:

host =
port = 4390
user = INA_USER
password = *******

SAP HANA Live Connection Prerequisites

1. Configure Public URL (XS)

To access information views in a HANA tenant database from SAP Analytics Cloud, the HANA XS server needs to listen to a public URL. It is not required to register the public URL with a public DNS. Only the computer accessing SAC needs to be able to resolve the address. This means that even the local hosts file can be used for name resolution. More common will be DNS registration inside the corporate network.

## execute as INI ADMIN on SYSTEMDB
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'database', 'HXE') 
 SET ('public_urls', 'http_url') = '' 
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'database', 'HXE') 
 SET ('public_urls', 'https_url') = '' 

For testing, you can add the FQDN of the host to your local hosts file (Linux, macOS /etc/hosts; Windows %WINDIR%\system32\drivers\etc)       localhost

2. Certify Public URL (XS)

The public URL needs to be signed by a certificate authority (CA). Digital web server certificates are provided by companies like DigiCert and Symantec (random list). For corporate environments, this service is typically by the IT department (SAP colleagues, visit Global PKI Certificate Management).

The public/private keys of the PSE (Personal Security Environment) of the HTTP Server (Web Dispatcher) are signed with host name only (CN=sid-hxe in case of HANA express). Recreate the SAPSSLS PSE with proper identification and with the CN corresponding to the public URL, e.g.


Then generate the CSR (certificate sign request), upload it to the CA and import the web server certificate.

Note that you have to import the full certificate trust chain:

  • Top: X.509 certificate received from the CA;
  • Middle: any intermediate certificate;
  • Bottom: (Global) Root Certificate

Typically, the CA provides just the signed certificate and you have to download the other from their website. Open the certificate as text file and copy/paste the content to the Import CA Response field. 

You can see this in action at time stamp 6:40 of the video

Should you use a Corporate CA (e.g. SAP) and not a global one (e.g. DigiCert), make sure to import the certificate trust chain on your client computer. Without the chain, browsers cannot trust the server certificate. Corporate client computers typically come with corporate certificates installed but should you have powered up a client with a cloud provider, you will have to import corporate root certificates yourself. 

In the video tutorial, we use the SAP Web Dispatcher to recreate the PSE, generate the CRS and import the certificate. You can access the tenant database web dispatcher using the URL configured above with path:

To connect to the Web Dispatcher, we need the WebDispatcherAdmin role. Any user could be used but a least-privileged user approach is generally recommended. In the code example below we create the XS_ADMIN user and grant the user the WebDispatcherAdmin role.

CREATE USER xs_admin PASSWORD  ****;
CALL GRANT_ACTIVATED_ROLE('sap.hana.xs.wdisp.admin::WebDispatcherAdmin','XS_ADMIN');

[2019.05] SAP Cloud Analytics Live Connections: 2. Certify Public URL (XS) – SAP Digital Enablement




For the tutorial videos, we used the SAP HANA, express edition system as provided by SAP Cloud Appliance Library. This development environment already includes the required EPMMDS plug-in. A standard “out-of-the-box” SAP HANA 2.0 SPS 01 platform edition does not include the EPMMDS component, so you would need to install it. The component is included with the media set or can be downloaded from the SAP ONE Support Launchpad, Software Downloads (“SAP HANA EPM-MDS”).

Use the platform lifecycle management tool (hdblcm) to install it. The web interface is accessible from HANA cockpit.

./hdblcm --components=epmmds --action=install



To connect to the InA service we need the INA_USER role. Any user could be used but a least-privileged user approach is generally recommended. In the code example below we create the INA_USER user and grant the user the INA_USER role.

CALL GRANT_ACTIVATED_ROLE('sap.bc.ina.service.v2.userRole::INA_USER','INA_USER');

To access specific information views, we need to grant this user SELECT privileges on the views:


Verify connectivity with GetServerInfo:

Verify connectivity with GetResponse:{%22Metadata%22:{%22Expand%22:[%22Cubes%22]}}


If the user does not have the INA_USER role, the following error message is returned when saving the Live Connection configuration:

You are not authorized to query the remote system. 
Please ask your administrator to grant you the InA role.

The GetServerInfo URL returns the following error when the component is not installed.

{"Messages":[{"Number":42001,"Type":2,"Text":"InformationAccess Service GetServerInfo is not available. Install EPM."}]}

4. CORS Configuration InA Service (XS)

Cross-Origin Resource Sharing (CORS) needs to be enabled for the InA service. You can access the tenant database XS artifact administration tool using the URL configured above with path:

To connect to tool we need the RuntimeConfAdministrator role. Any user could be used but a least-privileged user approach is generally recommended. In the code example below we grant the role to the user created in step 2 above.

CALL GRANT_ACTIVATED_ROLE('sap.hana.xs.admin.roles::RuntimeConfAdministrator','XS_ADMIN');
CALL GRANT_ACTIVATED_ROLE('sap.hana.xs.admin.roles::SAMLViewer','XS_ADMIN');

Edit the CORS settings for the following package:


Add the following to Allowed Headers:


Add the following to Exposed Headers:


Select the following Allowed Methods:


Alternatively, you can perform this task using SQL.

  • Connect to XS Admin with a user with RuntimeConfAdministrator role.
  • Navigate to sap.bc.ina.service.v2 package (as shown in the print screen)
  • Select Reset on the bottom right menu bar
  • Execute the SQL script
  • Reload the page to verify the changes have been applied.


REM execute on <tenant_db>
REM execute with role sap.hana.xs.admin.roles::RuntimeConfAdministrator

SET "CONFIGURATION" = ' {"cors":{
WHERE "PACKAGE_ID" = 'sap.bc.ina.service.v2';

If CORS has not been configured for the InA service, the following error is returned when creating the Live Connection

Failed to connect to HANA system. 
Possible causes: CORS Settings; incorrect credentials. 
More information can be found on the troubleshooting page.


5. HTTP Server Session Timeout (XS)

Default value for the HTTP Server (XS Engine) session timeout parameter is 900 seconds. The SAP Analytics Cloud Online Help recommends 12 hours.

ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'database', 'HXE') 
SET ('httpserver', 'sessiontimeout') ='43200'

  • Hi,

    I set the CORS Allowed header to:


    and Exposed Header to


    Still I get this error..

    Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

    Any ideas on how to fix this?




    • Hi Ravi,

      If you configured the environment exactly as document (of which my blog is just a reproduction) and you encounter an issue / error than I would conclude you identified a bug.

      Although unfortunate for you, this is great news for SAP development and I am sure they would love to hear about it so it can either be fixed in the code or, in case the issue is caused by external factors, have it documented in a note so future customers won’t have this problem. Did you already submitted a ticket?

      Searching the error message a bit, revealed it appears not to be uncommon. Maybe this article can bring some inspiration

      Should the issue be identified, please follow up on this post. Sharing is caring. Thanks

  • Hi Denys,

    I have been trying to connect to an on-premise HANA DB via SAC.

    HDB version info:
    branch: fa/hana2sp05

    I am able to make a live connection as well. However, when I try to create a model out of this live connection. I get the no Data Source option to select from.

    I do have analytical views and tables created via the user.

    select privilege on _SYS_BIC schema  is also assigned.

    I checked the network tab, it makes a POST request - which is 403 Forbidden https://<on_premisehost>4300/sap/bc/ina/service/v2/GetResponse
    with  payload

    I have tried GET request - sap/bc/ina/service/v2/GetResponse?Request={"Metadata":{"Expand":["Cubes"]}}and also/GetServerInfo
    This returns the data indeed.

    User has the INA_USER role assigned as well.
    I checked CORS settings also.

    Can you please suggest what could be the reason for this.

    • Hi Gulshan Goyal,

      Did you check the notes?

      Component LOD-ANA


      There are a couple which reference protocol error #73, so it appears to be common.

      Should this not provide any solution, suggest to post the question on and tag with SAP Analytics Cloud to notify all those subscribed. 


        • The issue is resolved! I found the cause.

          There was web-dispatcher configuration setting missing.

          HANA on-premise has to explicitly mark cookies for access in third-party, or cross-site, contexts.

          Only cookies with the SameSite=None; Secure attributes will be available for cross-site access, and require secure HTTPS connections.

          More information regarding configuration can be found here

          BR, Gulshan

  • Hello Denys,


    we were not able to create live connection from SAC to HANA using Chrome browser.

    Following the note 2968494 we were able to do it using Firefox

    Also application team were not able to create a model (from the live data connection above)  using Chrome (the same with Edge) but only with Firefox

    But as far as I know the best browser for SAC is Chrome:

    What do you think about that?
    Many thanks
    Kind regards,
