go to record - last
It is also possible to sort the relationship in a way that the desired record is first after GTRR.
Write a script to do an unsort which will put the last record last when you finish then do a resort.
GTTR using table or list or report layout
Sort by ticket and event
Go to first or last record depending upon how you sorted the selection
goto the layout
find by ticket
sort by event
I'd script the second since i could pass the ticket number as a parameter making the script more useful.
Is TimeEvent in the same table as Ticket or is it a related child record?
