Hi @PandaDH ,
OK no issues for this you need to follow some steps.
Step - 1
you need to create two DateTime parameter and on the filter section put the Date field and select the filter type as Date Time Range and condition as Between.
Put both Start Date parameter and End Date Parameter as picture below.
Step -2
Then go to parameter section and select both parameter as parameter control on the analysis
Step -3
Then go to Start Date parameter control and set the time as 12:00:00
In the same ways you can set the time for the End Date Parameter
Note - On both the parameter I have selected today as the default date you can change the date as per your choice so that you can get your desired result.
Thanks & Regards
