It combines business intelligence, predictive, planning, and digital boardroom capabilities to analyze data from on-premise and cloud applications.   [SAP Analytics Cloud](https://learning.sap-press.com/bi/sap-analytics-cloud) provides live connections (online) and data acquisition (batch) connectivity. In SAP Analytics Cloud, you can create models from your data sources, build stories based on those models, and perform online analysis with and without any data replication. This feature allows SAP Analytics Cloud to be used in scenarios where data cannot be moved into the cloud for security or privacy reasons or where your data already exists on a different cloud system. With replication, data is imported (copied) to SAP Analytics Cloud’s [SAP HANA](https://learning.sap-press.com/sap-hana) database.   From a security perspective, SAP Analytics Cloud provides SAML 2 capabilities to enable single sign-on, simplifying authentication to SAP Analytics Cloud and connected data sources from your landscape. SAP Analytics Cloud provides the business logic and builds the queries required to see your browser’s data. Your browser in turn sends those queries, through the reverse proxy, down or through a direct live connection to the on-premise database. The results of those queries are returned to the browser, where any charts are rendered. Throughout the process, the browser is interacting with the reverse proxy or through direct live connection (cross-origin resource sharing, or CORS), which in turn sends out the requests to SAP Analytics Cloud or the remote data source, depending on each request’s path.   Older versions of SAP NetWeaver applications servers don’t support native CORS connections. SAP Note 2596285 explains how to circumvent this issue by using a so-called ICM script. However, [SAP BW/4HANA](https://learning.sap-press.com/sap-data-management#SAP-BW4HANA) supports CORS. You can quickly check it using Transaction UCONCOCKPIT for unified connectivity settings, which is shown below. Systems not supporting CORS usually don’t support this transaction.   ![Unified Connectivity (UCON) Administration in SAP BW/4HANA](https://blog.sap-press.com/hs-fs/hubfs/1635_04_049.png?width=1103&name=1635_04_049.png)   Unified Connectivity (UCON) is a tool to secure your system against intruders. For all kinds of communication scenarios, you can specify what is allowed and what is forbidden. The configuration of UCON is beyond the scope of this book. Therefore, we refer you to the documentation found at *[http://s-prs.co/v454427](http://s-prs.co/v454427)*.   With SAML 2 and UCON in place, your system should be secure enough to proceed with CORS.   CORS is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served. A web page may freely embed cross-origin web pages, images, stylesheets, scripts, iframes, and videos. The same-origin policy in browsers is an essential concept in the web application security model. Under the policy, a web browser permits scripts in a first web page to access data in a second web page, but only if both web pages have the same origin. It’s a critical security mechanism for isolating potentially malicious documents. In a live connection, a browser has to access both SAP Analytics Cloud for metadata and backend data sources (SAP HANA, SAP BW/4HANA, [SAP S/4HANA](https://learning.sap-press.com/sap-s4hana), or universes).   If you use UCON to configure CORS, as you do with SAP BW/4HANA, you need to check that the parameter icf/cors\_enabled is set to 1 in Transaction RZ11. As you can see in the figure below, the **Current Value** is **1**.   ![Checking CORS Enablement for SAP Analytics Cloud in SAP BW/4HANA](https://blog.sap-press.com/hs-fs/hubfs/1635_04_050.png?width=1100&name=1635_04_050.png)   On SAP Cloud Appliance Library, icf/cors\_enabled is disabled by default. To permanently enable CORS in your system parameters enter Transaction RZ10 and choose your default profile. Next, select **Extended maintenance** and click **Display**. You should see the screen shown below.   ![Enabling CORS for SAP Analytics Cloud in Transaction RZ10](https://blog.sap-press.com/hs-fs/hubfs/1635_04_051.png?width=1068&name=1635_04_051.png)   If parameter icf/cors\_enabled is set to 0, change it to 1 by clicking on the **Change** button (icon to the left showing a pencil). If the parameter does not exist yet, simply create it with key icf/cors\_enabled and value “1”. Click **Save** and return to activate your changed profile. If you get an error message telling you that the profiles selected don’t correspond to the profiles being used, synchronize them by choosing **Import profiles >** **Of active servers** from the **Utilities** menu, as shown below.   ![Importing Profiles from Active Servers in Transaction RZ10](https://blog.sap-press.com/hs-fs/hubfs/1635_04_052.png?width=945&name=1635_04_052.png)   *Editor’s note*: This post has been adapted from a section of the book [*SAP BW/4HANA 2.0: The Comprehensive Guide*](https://www.sap-press.com/sap-bw4hana-20_4544/?utm_source=sappressblog&utm_medium=referral&utm_campaign=Blogs&utm_term=chapter4&utm_content=1635)by Thorsten Lüdtke and Marina Lüdtke. ## Recommendation [![SAP BW/4HANA 2.0: The Comprehensive Guide](https://blog.sap-press.com/hs-fs/hubfs/social-suggested-images/f.hubspotusercontent00.nethubfs5707200ImagesBook%20Covers1635-1.png?width=170&name=f.hubspotusercontent00.nethubfs5707200ImagesBook%20Covers1635-1.png)](https://www.sap-press.com/sap-bw4hana-20_4544/?utm_source=sappressblog&utm_medium=referral&utm_campaign=Blogs&utm_term=chapter4&utm_content=1635) **SAP BW/4HANA 2.0: The Comprehensive Guide** Ready for SAP BW/4HANA 2.0?
