You can use updategrams to insert, update, and delete SAP Netweaver Gateway data. This guide shows how to use the CData BizTalk Adapter for SAP Netweaver Gateway to generate updategram schemas and instances.
In this article, you will create updategrams that can be executed by the CData BizTalk Adapter for SAP Netweaver Gateway. You will design a schema and use it as a template for generating insert, update, and delete updategrams.
Add the Adapter for SAP Netweaver Gateway to Your Project
Use the Add Adapter wizard to add the adapter to a BizTalk Server project in Visual Studio. You will use the adapter to query SAP Netweaver Gateway for metadata about the table you want to modify.
- Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
- Select Add Adapter Metadata in the resulting dialog box.
- In the resulting Add Adapter Wizard, select the CData BizTalk Adapter for SAP Netweaver Gateway from the list view.
- In the Port menu, leave the selection blank. Or, select a receive location or send port that has been configured to use the adapter.
- When you click Next, the Schema Wizard is displayed.
Generate a Schema for an Updategram
Follow the steps below to create a schema in a BizTalk Server project in Visual Studio.
- If you have not already done so, add the SAP Netweaver Gateway adapter to your project.
- On the Connection String page of the Add Adapter wizard, enter authentication credentials and other connection properties, if they were not already configured in the send port or receive location. 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.
See the "BizTalk Configuration" chapter in the help documentation for more information on the required connection properties.
- On the Schema Information page, click Send Port in the General Options section. Select Updategram from the CommandType menu. If you are using the adapter in a solicit-response send port, disable the One-Way option.
On the next page, Statement Information, select the type of the updategram: Insert, Update, or Delete. Select the Table name and the columns you want to include in the schema. If you want to update or delete, the Id column is required.
Note: When you create the updategram, you are limited to modifying the columns you include in the schema.
- Click Next to view a summary of the schema and finish the wizard to create the schema. The resulting .xsd file is added to your project.
Generate Insert, Update, and Delete Instance Messages
After you create the updategram schema, you can use the .xsd file to generate the updategram: Right-click the .xsd file and select Generate Instance. You can also use this file as a template to manually create updategrams. Below are example generated updategram instances for inserts, updates, and deletes:
Insert
An example of INSERT is below. In this instance, there is only an after block, which specifies how the data will change.
<ns0:parameters xmlns:ns0="http://www.cdata.com/SAPGatewayProvider">
<ns0:sync>
<ns0:before></ns0:before>
<ns0:after>
<ns0:SalesOrderLineItems ProductID="ProductID_0" Quantity="Quantity_1" />
</ns0:after>
</ns0:sync>
</ns0:parameters>
Update
An example of UPDATE is below. In this instance, there is both a before block (how the data currently exists in the table) and an after block (how the data will change).
<ns0:parameters xmlns:ns0="http://www.cdata.com/SAPGatewayProvider">
<ns0:sync>
<ns0:before>
<ns0:SalesOrderLineItems Id=001d000000YBRseAAH></ns0:SalesOrderLineItems>
</ns0:before>
<ns0:after>
<ns0:SalesOrderLineItems ProductID="ProductID_0" Quantity="Quantity_1" ></ns0:SalesOrderLineItems>
</ns0:after>
</ns0:sync>
</ns0:parameters>
Delete
An example for DELETE is below. The after block will be empty to show that it is removing the item.
<ns0:parameters xmlns:ns0="http://www.cdata.com/SAPGatewayProvider">
<ns0:sync>
<ns0:before>
<ns0:SalesOrderLineItems Id=001d000000YBRseAAH></ns0:SalesOrderLineItems>
</ns0:before>
<ns0:after></ns0:after>
</ns0:sync>
</ns0:parameters>
