Use the SQL Gateway and the ODBC Driver to set up a linked server for SAP Ariba Procurement data.
You can use the SQL Gateway to configure a TDS (SQL Server) remoting service and set up a linked server for SAP Ariba Procurement data. After you have started the service, you can use the UI in SQL Server Management Studio or call stored procedures to create the linked server. You can then work with SAP Ariba Procurement data just as you would a linked SQL Server instance.
Connect to SAP Ariba Procurement 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.
In order to connect with SAP Ariba Procurement, set the following:
- ANID: Your Ariba Network ID.
- ANID: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Buyer or Supplier API based on your business role (possible values are PurchaseOrdersBuyerAPIV1 or PurchaseOrdersSupplierAPIV1).
- Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).
Authenticating with OAuth
After setting connection properties, you need to configure OAuth connectivity to authenticate.
- Set AuthScheme to OAuthClient.
- Register an application with the service to obtain the APIKey, OAuthClientId and OAuthClientSecret.
For more information on creating an OAuth application, refer to the Help documentation.
Automatic OAuth
After setting the following, you are ready to connect:
-
APIKey: The Application key in your app settings.
OAuthClientId: The OAuth Client Id in your app settings.
OAuthClientSecret: The OAuth Secret in your app settings.
When you connect, the provider automatically completes the OAuth process:
- The provider obtains an access token from SAP Ariba and uses it to request data.
- The provider refreshes the access token automatically when it expires.
- The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.
Configure the TDS Remoting Service
See the SQL Gateway Overview for a guide to configure a TDS remoting service in the SQL Gateway UI. The TDS remoting service is a daemon process that listens for TDS requests from clients.
Create a Linked Server for SAP Ariba Procurement Data
After you have configured and started the daemon, create the linked server and connect. You can use the UI in SQL Server Management Studio or call stored procedures.
Create a Linked Server from the UI
Follow the steps below to create a linked server from the Object Explorer.
- Open SQL Server Management Studio and connect to an instance of SQL Server.
- In the Object Explorer, expand the node for the SQL Server database. In the Server Objects node, right-click Linked Servers and click New Linked Server. The New Linked Server dialog is displayed.
- In the General section, click the Other Data Source option and enter the following information after naming the linked server:
- Provider: Select "Microsoft ODBC Driver for SQL Server" or "Microsoft OLE DB Driver for SQL Server"
Data Source: Enter the host and port the TDS remoting service is running on, separated by a comma.
Note that a value of "localhost" in this input refers to the machine where SQL Server is running so be careful when creating a linked server in Management Studio when not running on the same machine as SQL Server.
- Catalog: Enter the CData system DSN, CData SAPAribaProcurement Sys.
- In the Security section, select the option to have the connection "made using this security context" and enter the username and password of a user you created in the Users tab of the SQL Gateway.
Create a Linked Server Programmatically
In addition to using the SQL Server Management Studio UI to create a linked server, you can use stored procedures. The following inputs are required:
- server: The linked server name.
- provider: Enter "MSOLEDBSQL", for the Microsoft OLE DB Driver for SQL Server.
datasrc: The host and port the service is running on, separated by a comma.
Note that a value of "localhost" in the datasrc input refers to the machine where SQL Server is running, so be careful when creating a linked server in Management Studio when not running on the same machine as SQL Server.
- catalog: Enter the system DSN configured for the service.
- srvproduct: Enter the product name of the data source; this can be an arbitrary value, such as "CData SQL Gateway" or an empty string.
-
Call sp_addlinkedserver to create the linked server:
EXEC sp_addlinkedserver @server='SAPAribaProcurement', @provider='MSOLEDBSQL', @datasrc='< MachineIPAddress >,1434', @catalog='CData SAPAribaProcurement Sys', @srvproduct=''; GO
-
Call the sp_addlinkedsrvlogin stored procedure to allow SQL Server users to connect with the credentials of an authorized user of the service. Note that the credentials you use to connect to the service must specify a user you configured on the Users tab of the SQL Gateway.
EXEC sp_addlinkedsrvlogin @rmtsrvname='SAPAribaProcurement', @rmtuser='admin', @rmtpassword='test', @useself='FALSE', @locallogin=NULL; GO
Connect from SQL Server Management Studio
SQL Server Management Studio uses the SQL Server Client OLE DB provider, which requires the ODBC driver to be used inprocess. You must enable the "Allow inprocess" option for the SQL Server Native Client Provider in Management Studio to query the linked server from SQL Server Management Studio. To do this, open the properties for the provider you are using under Server Objects -> Linked Servers -> Providers. Check the "Allow inprocess" option and save the changes.
Execute Queries
You can now execute queries to the SAP Ariba Procurement linked server from any tool that can connect to SQL Server. Set the table name accordingly:
SELECT * FROM [linked server name].[CData SAPAribaProcurement Sys].[SAPAribaProcurement].[Orders]
