I’m not aware of any method that automagically keeps track of that information.
If you do not see a field(s) that relates to a create Date/Time stamp, then have a problem.
Are you journaling the file? That would keep track of changes made to the file.
Use DSPFD and search for ‘jour’.
<pre> File is currently journaled . . . . . . . . : No </pre>
Reminder: If the file was created with reuse set to *YES, then the RRN sequence for inserts is no longer valid.
Reuse deleted records . . . . . *YES *YES, *NO
