If you've created custom triggers, stay current with product releases to identify any changes to our TDTM framework that might require changes to your custom triggers.
For example, EDA version 1.100 introduced the TDTM_Event, TDTM_Lead, TDTM_Task, and TDTM_User Trigger Handlers. If you had previously created custom triggers for any of these objects, we recommend deleting your custom triggers. Maintaining one trigger for each object helps avoid re-entrancy issues.
