SYMPTOMS
When you have a rule set in Microsoft BizTalk Server that uses the same condition two times, one time with a NOT operator and one time without, your rule set may not be evaluated correctly. For example, you have the following rule set configured: OR

AND Field A Exists in XDoc NOT Field B exists in XDoc AND Field B Exists in XDoc NOT Field A exists in XDoc Because the condition &quot;Field A Exists in XDoc&quot; is used both with a NOT operator and without a NOT operator, the expression in both tests may evaluate the same way: either TRUE or FALSE.
