You may receive a "Message has not been initialized in construct statement" error message when you build a BizTalk Server 2004 solution in Visual Studio

When you build a Microsoft BizTalk Server 2004 solution in Microsoft Visual Studio, you may receive an error message that is similar to the following:

This behavior may occur when you do not include all the message assignments of a specific message within the same construct message shape.

When you construct a message, you specify all the message variables. Then, you make assignments to the message or its parts. If part of a specific message assignment is included in a separate construct message shape, you may receive the error message that is described in the "Symptoms" section.

To resolve this behavior, make sure that you include all parts of a specific message assignment in the same construct message shape.

This behavior is by design.
