How to Use a Microsoft Access Database to Update SAP Netweaver Gateway Data in Real Time

CData ODBC drivers connect your data to any database management tool that supports Open Database Connectivity (ODBC). This includes many of the most popular productivity tools, adding new capabilities for document sharing and collaboration. Using the CData ODBC driver for SAP Netweaver Gateway, you can update live SAP Netweaver Gateway data in Microsoft Access; for example, you can make updates that can be immediately seen by other users.

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.

Create a Linked Table to SalesOrderLineItems Data

Follow the steps below to create a linked table, which enables you to access live SalesOrderLineItems data.

1. On the External Data tab in Access, click ODBC Database. 👁 Use the Get External Data wizard to work with ODBC data sources in Access.
   
2. Select the option to link to the data source. A linked table will enable you to read from and write data to the SalesOrderLineItems table. 👁 Linked Tables enable you use the live connection to SAP Netweaver Gateway that is provided by the driver.
   

3. Select the CData SAP Netweaver Gateway data source from the Machine Data Source tab.

   👁 DSNs listed in the Get External Data wizard.
   
4. Select the SalesOrderLineItems table. For more information on this table, see the "Data Model" chapter in the help documentation. 👁 Available tables. (Google is shown.)
   

5. Double-click the linked table to make edits. The linked table will always have up-to-date data and any changes will be reflected back to the underlying table.
