SYMPTOMS

Reason: Cannot locate document specification because multiple schemas matched the message type "namespace#rootname".

This issue occurs when you receive a message in BizTalk Server.

CAUSE

This issue occurs when the combination of the target namespace and root name of two or more deployed schemas is not unique.

Note This issue occurs even if the target namespace and root names of those schemas have uppercase and lowercase differences.

RESOLUTION

To resolve this issue, verify that the combination of the target namespace and root name of all deployed schemas is unique.

MORE INFORMATION

This issue does not occur if the following conditions are true:

Binary collation is set on an instance of Microsoft SQL Server that is used by BizTalk Server 2006 or BizTalk Server 2004.
The namespace and root name of those schemas have uppercase and lowercase differences.

BizTalk Server 2006 and BizTalk Server 2004 contain a uniqueness constraint that enforces unique target namespace and root names for schemas. If you use two namespaces that vary only by case, the BizTalk database must be installed by using a case-sensitive collation.
