Configure dynamic ports in the SAP adapter

  • Article

Use message context properties

In BizTalk Server, you can configure dynamic ports for a WCF-Custom adapter. Because SAP adapter is a WCF-based adapter, you can dynamically configure a port for the SAP adapter by using message context properties.

For the SAP adapter, the URI, action, and binding might be determined from a property on an incoming message, and then specified in the Expression shape, as shown in the following example:

Request2=Request1;  
Request2(WCF.Action)="http://Microsoft.LobServices.Sap/2007/03/Rfc/RFC_CUSTOMER_GET";  
Request2(WCF.BindingType)="sapBinding";  
Request2(WCF.UserName)="YourUserName";  
Request2(WCF.Password)="YourPassword";  
SendPort(Microsoft.XLANGs.BaseTypes.Address)="sap://CLIENT=800;LANG=EN;@A/YourSAPHost/00";  
SendPort(Microsoft.XLANGs.BaseTypes.TransportType)="WCF-Custom";

Note

If you are using a WCF-SAP adapter in BizTalk Server Administration console, you can also specify the transport type as SendPort(Microsoft.XLANGs.BaseTypes.TransportType)="SAPAdapter", where SAPAdapter is the name with which you added the WCF-SAP adapter in BizTalk Server Administration console.

In the preceding example:

  • Request2 message is being created from Request1 message. Both the messages map to an operation schema, which is generated using the Consume Adapter Service BizTalk Project Add-in.

  • SendPort is the name of the logical send port in the BizTalk orchestration.

    The Expression shape is part of the BizTalk orchestration. When you deploy the orchestration, the WCF-Custom send port is also created.
