Use the Connect Server to Access SQL Analysis Services Data in Microsoft Power Pivot

This article will explain how to use the Connect Server to provide SQL Analysis Services data as OData services and then consume the data in Microsoft Excel's Power Pivot business intelligence tool. Follow the steps below to retrieve SQL Analysis Services data in Power Pivot.

Connect to SQL Analysis Services from Power Pivot

To work with live SQL Analysis Services data in Power Pivot, we need to connect to SQL Analysis Services from Connect Server, provide user access to the new virtual database, and create OData endpoints for the SQL Analysis Services data.

Add a Connect Server User

Create a User to connect to SQL Analysis Services from Power Pivot through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to SQL Analysis Services from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open Connect Server and click Connections
2. Select "SQL Analysis Services" from Available Data Sources
3. Enter the necessary authentication properties to connect to SQL Analysis Services.

   To connect, provide authentication and set the Url property to a valid SQL Server Analysis Services endpoint. You can connect to SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to SQL Server Analysis Services.

   To secure connections and authenticate, set the corresponding connection properties, below. The data provider supports the major authentication schemes, including HTTP and Windows, as well as SSL/TLS.

   • HTTP Authentication

     Set AuthScheme to "Basic" or "Digest" and set User and Password. Specify other authentication values in CustomHeaders.

   • Windows (NTLM)

     Set the Windows User and Password and set AuthScheme to "NTLM".

   • Kerberos and Kerberos Delegation

     To authenticate with Kerberos, set AuthScheme to NEGOTIATE. To use Kerberos delegation, set AuthScheme to KERBEROSDELEGATION. If needed, provide the User, Password, and KerberosSPN. By default, the data provider attempts to communicate with the SPN at the specified Url.

   • SSL/TLS:

     By default, the data provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

   You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

   See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add SQL Analysis Services OData Endpoints in Connect Server

After connecting to SQL Analysis Services, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the SQL Analysis Services database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Import SQL Analysis Services Tables in Power Pivot

Follow the steps below to import tables that can be refreshed on demand:

1. In Excel, click Data -> Get Data -> From Other Sources -> From OData Feed
2. Fill out the OData feed URL (e.g. http://localhost:8080/odata.rsc)
3. On the next screen, select Basic and configure the username and password. Password should be your auth token.

4. Select the tables that you would like to import into Excel

5. After selecting your table(s) and clicking Load, you should see the data appear in an Excel spreadsheet

6. Now, click the Power Pivot tab on the ribbon, and then select Add to Data Model. This can now work with your SQL Analysis Services data in Power Pivot.
