Hello Martina -

Thanks so much. I appreciate the help!

Interestingly the Record Validation rule will not fire when a record is simply marked for deletion. Worse case I could set a DELETE TRIGGER and log such deletions. Using both the "last updated" column and the log would allow for reporting of all changes and deletions (adds will be handled via a column default value) after a given datetime value. I think that will work.

Thanks again.
