How to Generate SQL Command Schemas for the CData BizTalk Adapter for SAP

The CData BizTalk Adapter makes it easy to process SAP data in BizTalk by returning the data as XML. You can use this data in a BizTalk orchestration by creating an XML schema file for the table you want to access in BizTalk.

This article will show how to generate a schema to process SAP data retrieved using the CData BizTalk Adapter. You will generate a schema for a SELECT command.

You can use the CData BizTalk Adapter for SAP to execute standard SQL commands to SAP.

Add the Adapter for SAP to Your Project

Follow the steps below to add the adapter to a BizTalk Server project.

  1. If you have not already done so, create a new BizTalk Server project in Visual Studio.
  2. Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
  3. Select Add Adapter Metadata in the resulting dialog box.
  4. In the resulting Add Adapter wizard, select the adapter from the list.
  5. In the Port menu, leave the selection blank. You can also select a receive location or send port that has the adapter configured as its transport type.

Generate a Schema for an SQL Command

After you select the adapter in the Add Adapter wizard, the Schema wizard is displayed. Follow the steps below to configure connection properties and retrieve the metadata for the results of the command.

  1. In the Connection String page, enter authentication credentials and other connection properties, if you did not select an adapter that you have already configured in your BizTalk application. Below is a typical connection string:

    Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:\\mysapschemafolder;

    SAP への接続はlibrfc32.dll、librfc32u.dll、NetWeaver、Web Services (SOAP) のどれかで行います。 ConnectionType 接続プロパティをCLASSIC (librfc32.dll)、CLASSIC_UNICODE (librfc32u.dll)、NETWEAVER、SOAP に設定します。

    SOAP を使う場合、Client、RFCUrl、SystemNumber、User、Password のプロパティを設定します。

    それ以外の方法の場合、Host、User、Password、Client、SystemNumber を指定します。

    Note: librfc32.dll やその他のSAP 接続には対応しておりません。SAP インストールから対応する接続モジュールをマシンにインストールしておいてください。

    詳細情報はobtaining the connection properties を参照してください。

  2. In the General Options section on the next page, Schema Information, select Send Port or Receive Location, depending on the adapter configuration.
  3. If you want to generate the schema for the entire result set, select the Single Message option in the Message Mode menu. If you want to generate one schema for each row in the result set, select the Message Per Row option and confirm that the root element of the message is 'row'.
  4. In the Command Type menu, select SQL Command.
  5. In the SQL Command Text box on the Statement Information page, enter an SQL command. (If you have configured a receive location or send port, the SQL command you configured is entered in the box.) This example uses the query below:

    SELECT * FROM MARA

  6. Confirm the settings in the summary displayed by the wizard and click Finish to generate the schema.xsd file.
