PROBLEM: Several different schedules in BizApp were behaving erratically and seemed to be changing their contents randomly
SOLUTION: The scheduling issues in this case were related to a schedule (or more) being control linked to others. Control Linking can be set to make changes to another schedule based on changes in the current one. In this scenario, control links were used without a full understanding of the changes they will make automatically. The solution was to remove the control linking on the affected schedules.
