FIX: "Object reference not set to an instance of an object" error message when you use Commerce Server adapters for BizTalk Server from Commerce Server 2007 to receive orders

Consider the following scenario:

• You have a computer that is running Microsoft BizTalk Server 2006 or that is running Microsoft BizTalk Server 2006 R2.
• You install Commerce Server adapters for Microsoft BizTalk Server on the computer.
  
  Note Commerce Server adapters for BizTalk Server in a discussion are included in Commerce Server 2007.
• You create and configure a receive location for an endpoint by using the Orders receive adapter to receive orders from Commerce Server 2007.

In this scenario, the receive location for the endpoint may stop responding intermittently. Additionally, an error message that resembles the following is logged in the Application log:

Note This issue typically occurs when there is network latency, or when the computer that is running the Orders Web service also has other processes running. For example, a large catalog import operation is being executed.

This issue occurs because the batch of transactions is not committed to a message box in BizTalk Server when it tries to receive orders from Commerce Server 2007.
