ThankQ will automatically generate a new Event Id starting with EVT for the Event that you have copied, unless you have set the Coding Control Lookup Value to Yes in Lookup Values.
If this has been set to Yes, the Event ID will be sequentially incremented using the existing Event Id.
For example, if you copy Events ID CONTRA001, the new event that is created as a result of the copy will have an Event ID of CONTRA002.
