Up until recently, the system was correctly blocking the same SO from being shipped/invoiced more than once before running Daily Sales Reports/Updates.  For some unknown reason that function is no longer working.  Knowledgebase article 109989 (link below) categorizes this behavior as a defect but it used to work.  Any ideas on what may have caused the function to fail or how to re-enable it short of reinstalling the software?
