Configure a One-Way Send Port for the CData BizTalk Adapter for SAP Netweaver Gateway



Use the adapter for SAP Netweaver Gateway with a one-way send port to execute updategrams and data manipulation SQL in BizTalk.

This section provides step-by-step instructions for creating, configuring, and testing a static one-way send port using the CData BizTalk Adapter for SAP Netweaver Gateway. You can use static one-way send ports to execute updategrams, SQL commands, and stored procedures. Send ports are useful for operations that modify SAP Netweaver Gateway data but do not have any response data. Typically, this would be DELETE or UPDATE SQL commands or updategrams, and occasionally stored procedure operations.

If you want to trigger actions that will return a response, such as executing SELECT commands or retrieving the Id of a record that you have created, use a solicit-response send port.

Create and Configure the One-Way Send Port

Create a static one-way send port and configure it to use the SAP Netweaver Gateway adapter as its transport type.

  1. If you have not already done so, open your BizTalk application in the BizTalk Administration Console.
  2. In the node for your BizTalk application, right-click Send Ports and select New -> Static One-Way Send Port. The send port properties dialog is displayed.
  3. In the Name menu, enter a name for the send port.
  4. In the Type menu, select CData.SAPGateway.
  5. In the Send Pipeline menu, select the default option, PassThruTransmit.

Configure the Adapter

Define the command that the adapter will execute in the Transport Properties dialog.

  1. In the send port properties, click the Configure button. The CData.SAP Netweaver Gateway Transport Properties dialog is displayed.
  2. In the CommandType property, select the command type you want.
  3. If you want to execute an SQL command, enter the command in the SQL Command box.
Refer to the "Adapter Configuration" chapter in the help documentation for a description of the various properties and their functions.

Configure the Connection to SAP Netweaver Gateway

Configure credentials and other properties required to connect to SAP Netweaver Gateway in the Connection String Options dialog.

  1. In the send port properties dialog, click Configure. The adapter properties dialog is displayed.
  2. Click the button in the Connection String property.
  3. Click the box in the Connection String property. The Connection String Options dialog is displayed.
  4. Enter connection properties. Below is a typical connection string: User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;InitiateOAuth=GETANDREFRESH

    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.

  5. Click Test Connection to verify the values and test connectivity.
Refer to the "Connection String Options" chapter in the help documentation for a description of the various properties and their functions.

After you connect successfully and define the command the adapter will execute, the send port is ready for use. See the following section for an example of using a one-way send port in a simple application. The application reads updategram commands contained in a file and uses a send port to execute the command.

In the example, filters are used to move the messages that contain the updategram from the receive location to the send port. See the following section for more information on filters.

Create Filters to Route BizTalk Messages Through an Application

To associate a send port with the messages you want, create a filter rule in the Filters section of the properties for that send port. Messages matching the criteria will be routed to the send port. See the following example to filter on a receive location.

Example: Execute Updategrams with a One-Way Send Port

This section shows how to use a one-way send port in a simple application. The application reads updategram commands contained in a file and executes the commands:

  1. A one-way receive location picks up the XML document containing the updategram.
  2. The receive location creates a BizTalk message containing the results of the command.
  3. A one-way send port filters on the URI of the receive location. The document is routed to the one-way send port.
  4. The send port executes the updategram command.

As in the preceding example, the followings steps show how to set up a receive location to read updategrams from a file and use a send port to execute the commands:

  1. Create and configure a static one-way receive location. Use the File transport type. You can follow the same procedure to create and configure a receive location for the CData BizTalk Adapter for SAP Netweaver Gateway.
  2. Create a static one-way send port.
  3. In the send port properties, click Filters.
  4. In an empty property, set the following values:
    Property
    Select BTS.InboundTransportLocation from the menu.
    Value
    Enter the URI of the newly created one-way receive location.
