Use the CData ODBC Driver for SAP Netweaver Gateway in MicroStrategy

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData ODBC Driver for SAP Netweaver Gateway, you gain database-like access to live SAP Netweaver Gateway data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a database instance for SAP Netweaver Gateway in MicroStrategy Developer and creating a Warehouse Catalog based on SAP Netweaver Gateway data.

The CData ODBC driver offers unmatched performance for interacting with live SAP Netweaver Gateway data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to SAP Netweaver Gateway, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP Netweaver Gateway and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze SAP Netweaver Gateway data using native MicroStrategy data types.

Connect to SAP Netweaver Gateway as an ODBC Data Source

Information for connecting to SAP Netweaver Gateway follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for SAP Netweaver Gateway must be installed on the machine hosting the connected MicroStrategy Intelligence Server).

SAP Gateway allows both basic and OAuth 2.0 authentication. You can use basic authentication to connect to your own account, or you can use OAuth to enable other users to retrieve data from your service with their accounts. In addition to authenticating, set the following connection properties to access SAP Gateway tables.

• Url: Set this to the URL of your environment, or to the full URL of the service. For example, the full URL might appear as: https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/. In this example, the environment URL would just be: https://sapes5.sapdevcenter.com.
• Namespace: Set the appropriate Service Namespace. In the example above, IWBEP is the namespace. It is optional if the full URL to the service is specified.
• Service: Set this to the service you want to retrieve data from. In the example above, the service is GWSAMPLE_BASIC. It is not required if the full URL is specified.

Authenticate via Basic Authentication

In basic authentication, you use your login credentials to connect. Set the following properties:

• User: This is the username you use to log in to SAP Gateway.
• Password: This is the password you use to log in to SAP Gateway.

Authenticate via OAuth Authentication

You can connect to SAP Gateway using the embedded OAuth connectivity (without setting any additional authentication connection properties). When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for SAP Netweaver Gateway in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a SAP Netweaver Gateway Database Instance in MicroStrategy Developer

You can connect to SAP Netweaver Gateway in MicroStrategy Developer by adding a database instance based on the CData ODBC Driver for SAP Netweaver Gateway.^*

1. Open MicroStrategy Developer and select a Project Source.
2. Navigate to Administration -> Configuration Managers -> Database Instances and right-click to add a new instance.
3. Name the instance, select Generic DBMS as the database connection type, and create a new database connection.
4. In the database connection wizard, name the connection and create a new Database Login name, using filler values for the user and password.
5. Select the DSN that you configured earlier as the ODBC data source (i.e., CData SAPGateway Sys).
6. Select the newly created database connection.
7. In the Project Source, right-click the project and open the Project configuration.
8. Navigate to Database Instances and select the newly created database instance.
9. Close MicroStrategy Developer and restart the connected MicroStrategy Intelligence Server to complete the database instance creation.

With the database instance configured, you will now be able to connect to SAP Netweaver Gateway data from the Warehouse Catalog and Data Import.

Connect to SAP Netweaver Gateway Data from the Warehouse Catalog

Once you have created a database instance based on the ODBC Driver for SAP Netweaver Gateway, you can connect to data from the Warehouse Catalog.

1. Select your project and click Schema -> Warehouse Catalog.
2. In the Read Settings for the Catalog, click Settings and set the queries to retrieve the schema:
   • To retrieve the list of tables, use the following query:

     SELECT 
       CatalogName NAME_SPACE,
       TableName TAB_NAME 
     FROM 
       SYS_TABLES
             

   • To retrieve the list of columns for selected tables, use the following query:

     SELECT DISTINCT 
       CatalogName NAME_SPACE, 
       TableName TAB_NAME, 
       ColumnName COL_NAME, 
       DataTypeName DATA_TYPE, 
       Length DATA_LEN, 
       NumericPrecision DATA_PREC, 
       NumericScale DATA_SCALE 
     FROM 
       SYS_TABLECOLUMNS 
     WHERE 
       TableName IN (#TABLE_LIST#) 
     ORDER BY
       1,2,3
             

3. Select tables to be used in the project.
