Import SAP Netweaver Gateway Data into Microsoft Power Query

The Connect Server enables you to use Web services to connect to and query SAP Netweaver Gateway data. This article details how to import an OData feed of SAP Netweaver Gateway data into Microsoft Power Query.

Connect to SAP Netweaver Gateway from Power Query

To work with live SAP Netweaver Gateway data in Microsoft Power Query, we need to connect to SAP Netweaver Gateway from Connect Server, provide user access to the new virtual database, and create OData endpoints for the SAP Netweaver Gateway data.

Add a Connect Server User

Create a User to connect to SAP Netweaver Gateway from Microsoft Power Query 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 SAP Netweaver Gateway 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 "SAP Netweaver Gateway" from Available Data Sources
3. Enter the necessary authentication properties to connect to SAP Netweaver Gateway.

   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.

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 SAP Netweaver Gateway OData Endpoints in Connect Server

After connecting to SAP Netweaver Gateway, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the SAP Netweaver Gateway 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 such as Ajax, 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.

Connect to SAP Netweaver Gateway Data from Power Query

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

1. Configure the Connect Server to use a version of the OData protocol that is recognized by Power Query. In the Connect Server administration console, click Settings -> Server and change the value of the Default Version property to 3.0.

2. From the ribbon in Excel, click Power Query -> From Other Data Sources -> From OData Feed, and enter the OData URL:

   https://your-server:8032/api.rsc

3. Next, define authentication credentials and set privacy levels. Select Basic authentication and enter the credentials for a user authorized to make requests. Specify the Username field and enter the user's authtoken in the Password field.

   To change the authentication scheme that Power Query will use, click Power Query -> Data Source Settings. Select the OData feed from the list and then click "Edit Permissions..." Select the privacy level from the menu.

4. You can now access SAP Netweaver Gateway data in Power Query. In the Navigator expand the node for the OData feed, right-click a table, and click Edit to open the Query Editor. This will display the table data.
