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:
Because the condition "Field A Exists in XDoc" 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.
Field A Exists in XDoc
Field B exists in XDoc
Field B Exists in XDoc
Field A exists in XDoc
