Need help with complex DAX question

Sample source data would really help but maybe this:

EVALUATE
ADDCOLUMNS ( 
	CALCULATETABLE ( 
		ADDCOLUMNS ( 
			SUMMARIZE ( 
				NATURALLEFTOUTERJOIN ( 
					Calendar544W,
					TimesheetFacts
				),
				Employees01[Person],
				TimesheetFacts[CMHRWRKS],
				TimesheetFacts[CMHRWRKI],
				Calendar544W[Date],
				Calendar544W[WeekdayNum],
				Calendar544W[IsPublicHoliday]
			),
			"Schedule", 
				MAXX ( 
					FILTER ( 
						TimesheetFacts,
						Employees01[Person] = EARLIER( Employees01[Person] 
                                        ),
			                TimesheetFacts[CMHRWRKS]
				)
		),
		FILTER ( 
			Calendar544W,
			Calendar544W[WeekYearNum] = 202001
		),
		FILTER ( 
			Employees01,
			Employees01[Person] = 537 || Employees01[Person] = 125
		)
	),
    "# Gross hrs", CALCULATE ( SUM ( TimesheetFacts[KMHRCATSH] ) )
)
ORDER BY [Date], [Person]
