Author and Share Power BI Reports on Real-Time SAP Netweaver Gateway Data

With built-in support for ODBC on Microsoft Windows, CData ODBC Drivers provide self-service integration with self-service analytics tools such as Microsoft Power BI. The CData ODBC Driver for SAP Netweaver Gateway links your Power BI reports to operational SAP Netweaver Gateway data. You can monitor SAP Netweaver Gateway data through dashboards and ensure that your analysis reflects SAP Netweaver Gateway data in real time by scheduling refreshes or refreshing on demand. This article details how to use the ODBC driver to create real-time visualizations of SAP Netweaver Gateway data in Microsoft Power BI Desktop and then upload to Power BI.

The CData ODBC Drivers offer unmatched performance for interacting with live SAP Netweaver Gateway data in Power BI due to optimized data processing built into the driver. When you issue complex SQL queries from Power BI 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 Power BI data types.

Connect to SAP Netweaver Gateway as an ODBC Data Source

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.

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.

After creating a DSN, follow the steps below to connect to the SAP Netweaver Gateway DSN from Power BI Desktop:

1. Open Power BI Desktop and click Get Data -> ODBC. To start Power BI Desktop from PowerBI.com, click the download button and then click Power BI Desktop.
2. Select the DSN in the menu. If you know the SQL query you want to use to import, expand the Advanced Options node and enter the query in the SQL Statement box.
3. Select tables in the Navigator dialog.

4. Click Edit to edit the query. The table you imported is displayed in the Query Editor. In the Query Editor, you can enrich your local copy of SAP Netweaver Gateway data with other data sources, pivot SAP Netweaver Gateway columns, and more. Power BI detects each column's data type from the SAP Netweaver Gateway metadata retrieved by the driver.

   Power BI records your modifications to the query in the Applied Steps section, adjusting the underlying data retrieval query that is executed to the remote SAP Netweaver Gateway data. When you click Close and Apply, Power BI executes the data retrieval query.

   Otherwise, click Load to pull the data into Power BI.

Create Data Visualizations

After pulling the data into Power BI, you can create data visualizations in the Report view by dragging fields from the Fields pane onto the canvas. Follow the steps below to create a pie chart:

1. Select the pie chart icon in the Visualizations pane.
2. Select a dimension in the Fields pane: for example, ProductID.
3. Select a measure in the Quantity in the Fields pane: for example, Quantity.

You can change sort options by clicking the ellipsis (...) button for the chart. Options to select the sort column and change the sort order are displayed.

You can use both highlighting and filtering to focus on data. Filtering removes unfocused data from visualizations; highlighting dims unfocused data. You can highlight fields by clicking them:

You can apply filters at the page level, at the report level, or to a single visualization by dragging fields onto the Filters pane. To filter on the field's value, select one of the values that are displayed in the Filters pane.

Click Refresh to synchronize your report with any changes to the data.

Upload SAP Netweaver Gateway Data Reports to Power BI

You can share reports based on ODBC data sources with other Power BI users in your organization. To upload a dashboard or report, log into PowerBI.com, click Get Data -> Files, and navigate to a Power BI Desktop file or Excel workbook. You can then select the report in the Reports section.

Refresh on Schedule and on Demand

You can use the Power BI Personal Gateway to automatically refresh the dataset associated with your report. You can also refresh the dataset on demand in Power BI. After installing the Personal Gateway, follow the steps below to schedule refreshes for an ODBC DSN:

1. Log into Power BI.
2. In the Dataset section, right-click the SAP Netweaver Gateway Dataset.
3. Click Schedule Refresh.
4. In the settings for your dataset, expand the Data Source Credentials node and click Edit Credentials in the ODBC section.
5. Expand the Schedule Refresh section, select Yes in the Keep Your Data Up to Date menu, and specify the refresh interval.

You can now share real-time SAP Netweaver Gateway reports through Power BI.
