Hi

I'm trying to use the BizTalk adapter to connect to Dynamics AX, but I get
this error message:

An unexpected failure occurred while processing a message. The following
error has occured: Object reference not set to an instance of an object.

The error occurs when BizTalk tries to send the message to Dynamics AX.

I have followed the description in the document "Configuring the Application
Integration Framework (AIF) BizTalk Adapter for Data Exchange".

The proxy user is defined, it's a domain user
The BizTalk process user is a domain user, also defined in Dynamics
The gateway user is a domain user, also defined in Dynamics
BizTalk Server and Dynamics AX AOS is on the same server

I'm using following SW:
Windows Server 2003, Enterprise Edition
BizTalk Server 2006 R2
Dynamics AX 4.0 SP2

Does anyone knows what the problem is? I can provide more information if it
is needed.
