Extenuating Circumstances for Exactly-Once Processing
 
Circumstances in which Duplicate Messages Can Be Processed
Circumstances in which New Messages Are Treated as Duplicates
Although Integration Server provides robust duplicate detection capabilities, activity outside of the scope or control of the Integration Server retrieving the message might cause a trigger to process a message (document) more than once. Alternatively, situations can occur where Integration Server might determine a message is a duplicate when it is actually a new message.
