The self-maintaining default rows setting on the Timesheet Preferences window gives you the option of automatically updating your default rows. If you enter a number of days for this preference, your default rows are automatically updated every Monday. The existing default rows are deleted and new default rows are created based on timesheet rows which have time within the number of days you specified.
Exceptions Rows are not automatically created for:
Jobs which have been closed
Clients who are now inactive
Clients who have been marked as time exempt
Time Off
Tips for setting the number of days:
If your rows change frequently, specify a lower number of days. (For instance, somewhere in the range of 7 to 21 days)
If your rows do not change very often, set a higher number of days. (For instance, somewhere in the range of 30 to 45 days)
If you find that too many rows are being created, decrease the number of days.
If too many clients/jobs are being omitted from your default rows, key a higher number of days.
You can ignore this feature altogether by leaving the number of days blank and manually setting up your default timesheet in Default Row Setup. You can also change your mind any time. Just change the number of days or delete it and the following week the new rule will be followed as the new default for you.
