This is my Custom Function and I want to edit it

I think you almost had it but there is no reason for the let or case statement. This is simpler.

GetAsDate ( field ) - DayOfWeek ( field ) +2

Or use +1 instead of +2 to get Sunday instead of Monday. Personally I call it weekStart and add +1 in the function and add another +1 in the calculation when I call the weekStart function. There really is no need to have a weekStart and a weekStartMonday.

Of course you can use

GetAsDate ( EndDate ) - DayOfWeek ( EndDate ) +6

To correct data entry errors if you want the end date to be on a Friday. Thus when dealing with a working week (mon - fri) the +2 function can modify the start date to correct any errors to Monday and +6 to Friday. Be aware that if the EndDate has been entered as Sunday that will flip the end date correction through to the end of the following week.
