This fields update when the record is updated.
Option 1: Put the fields from each tab in a different related record
Option 2: set up script triggers on the fields in the tab that perform a script to update the field with Get ( CurrentDate ) when a field in the tab panel is modified.
Thanks! Do you recommend one option over the other, or is it a matter of preference/ depends on the project?
It's a matter of your skill set, your preferences and the design of your project. (And there's a Get ( CurrentTimeStamp ) function call that you can use instead of Get ( Currentdate )
