Connect to SAP ByDesign Data as a SQL Server Linked Server

SQL Server Linked Servers enable the SQL Server Database Engine to read data from remote data sources and execute commands against the remote database servers outside of the instance of SQL Server. Typically, linked servers are configured to enable the execution of a T-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. When paired with CData Connect Cloud, linked servers provides instant access to SAP ByDesign data from your SQL Server database. This article demonstrates how to connect to SAP ByDesign using Connect Cloud and query SAP ByDesign data in SQL Server Management Studio (SSMS).

CData Connect Cloud provides a pure SQL Server interface for SAP ByDesign, allowing you to query data from SAP ByDesign without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to SAP ByDesign, leveraging server-side processing to return the requested SAP ByDesign data quickly.

Configure SAP ByDesign Connectivity for SQL Server

Connectivity to SAP ByDesign from SQL Linked Servers is made possible through CData Connect Cloud. To work with SAP ByDesign data from SQL Linked Servers, we start by creating and configuring a SAP ByDesign connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "SAP ByDesign" from the Add Connection panel
3. Enter the necessary authentication properties to connect to SAP ByDesign.

   Set the following connection properties to connect to SAP ByDesign.

   • Url: Set this to the Url of your SAP ByDesign site. For example, https://test.sapbydesign.com
   • User: Set this to the username of your account.
   • Password: Set this to the password of your account.
   • CustomService or AnalyticsService: Only one of these must be specified. If you have a custom service you want to retrieve data from, specify CustomService. If you want to retrieve the reports of a analytical service, specify AnalyticsService.
     If neither is specified, 'cc_home_analytics.svc' will used as a default for the AnalyticsService property. If you are not sure what service to specify, you can always query the Services view to list available services.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add SAP ByDesign Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Connect to SAP ByDesign from SQL Server using Connect Cloud

To establish a connection from SQL Server Linked Server to the CData Connect Cloud Virtual SQL Server API, follow these steps.

1. Open Microsoft SQL Server Management Studio.
2. In the Object Explorer pane, open Server Objects, right-click Linked Servers, and select New Linked Server.
3. The New Linked Server dialogue opens. On the General page, enter the following information:
   • Enter a name for the server in the Linked server field.
   • Select the radio button Other data source and select SQL Server Native Client 11.0 as the provider.
   • In the Data source field, enter tds.cdata.com,14333
   • In the Catalog field, enter enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, SAPByDesign1).
4. Select the Security page. At the bottom, select the radio button labeled Be made using this security context and enter the following information:
   • Remote login - enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, test@cdata.com.
   • With password - enter the PAT you generated on the Settings page.
5. Click OK to create the server.
Your linked server can now be used to access the data in the data source you specified. If you need to access data from more sources, create another linked server for each one.

Execute Queries

You can now execute queries to the SAP ByDesign linked server from any tool that can connect to SQL Server. An example SQL query would be: SELECT * FROM [CDATA CONNECT CLOUD].[SAPByDesign1].[SAPByDesign].[[Inventory Balance]] We have successfully created a linked server that allows us to query SAP ByDesign data.
