FIX: You cannot use the WCF-based SAP adapter to send multiple IDOCs as a batch in BizTalk Adapter Pack 2.0

This article applies to the following product:
  • BizTalk Adapter Pack 2.0
Consider the following scenario:
  • You use the Microsoft Windows Communication Foundation (WCF)-based SAP adapter from Microsoft BizTalk Adapter Pack 2.0 to connect to an SAP system on a computer that is running Microsoft BizTalk Server.

    Note The WCF-based SAP adapter is also known as the Microsoft BizTalk Adapter for mySAP Business Suite 3.0.
  • You create a BizTalk project. Then, you use the Add adapter service reference wizard to create schemas for intermediate document (IDOC) inbound operations for the SAP system. The BizTalk project uses the WCF-based SAP adapter to receive IDOCs from the SAP system.
In this scenario, the maxOccurs setting for the iDocData node is set to 1 in the generated schema. For example, you receive the following message in the generated schema:
<idocData minOccurs="1" maxOccurs="1">
Therefore, you cannot send multiple IDOCs in a batch to the SAP system.

  • You cannot send multiple IDOCs as a batch even if you manually change the maxOccurs setting to a value that is larger than 1 in the generated schema.
  • The issue does not occur when you use the WCF-SAP adapter that is included in Microsoft BizTalk Adapter Pack 2010 because the maxOccurs setting is set to 2147483647.
