Until 15.9.3 and 15.9.2.1, if a user goes in Timesheets - Grid, all the timesheets, including Timesheets for Closed Periods would be displayed.
This could lead to performance issues, especially if there is a large amount of timesheets in the system (hundreds of thousands)
The workaround would be to use default views and advise all users against displaying all timesheets
Resolution
Change of Behavior:
Starting 15.9.3 and patch 15.9.2.1, the timesheets for Closed Periods will no longer display by default in Timesheet Grid in Modern UX
Only timesheets from Open Time Periods will display
No additional actions required from the user
If you need to see timesheets from Closed time periods in MUX
A new field is added, that can be used to specifically select and show them:
Time Period Is Open
Set this to No, and it will return all the timesheets for Closed time periods.
If you set to Yes, it will display all the timesheets for Open time periods.
To display both Open and Closed time periods, select the below option Time Period Is Open Is Not Empty ( Note: The All option will no longer work as expected due to the change, Time Period Is Open Is Not Empty has to be used)
Note : We do not recommend using the Time Period Is Open - Not Empty filter often on an environment with many hundreds of timesheets. Other filters should also be used to avoid a performance overhead on the Clarity application server
When the TIme Period is Closed and the Timesheet Is Open
For Closed time periods, the Timesheets that are Open and have never been opened/edited, will not display in Timesheet Grid in MUX
Those are considered to be virtual timesheets
To see them in MUX you will have to open the respective period for time entry
