Fixing the bug in the Modification Date

Tuesday 17 May 2022 @ 6:51 pm

A long time ago I wrote about a bug in Crystal Reports that affects two special fields:

  • Modification Date
  • Modification Time.

These fields show you when that report was last modified. If you open and refresh a report without changing anything the modification date and time should not change. This works most of the time, but it doesn’t work if you have a subreport.

This came up again this past week and after some discussion I thought of another article that I wrote in January about the options setting ‘Verify on first refresh”.  I ran a quick test and found that turning this setting off solved the problem. Apparently, doing that “Verify Database” counts as a report modification – but ONLY if there is a subreport in the report.  The behavior is different if there is no subreport.  This inconsistency is why I categorize this as a bug.

So if you are using the modification date (or modification time) in a report that has one or more subreports, you might want to turn this setting off.  It is found in File > Report Options.

And, if anyone finds an issue with turning off this setting, please let me know. I can’t think of one.
