CALCULATe WITH MONTH DATE CONDITION

[Anonymous]

Dear,

I need some help regarding a formula. In fact, I would like to do a kind of : 

IF(week(date) = 1; CALCULATE ([SUM OF TURNOVER]; 'Flag date for previous month' = "OK";

IF(week(date)> 1; CALCULATE ([SUM OF TURNOVER]; 'Flag date for current month' = "OK")

In fact, I would like to calculate the sum of turnover of the previous month if we are in the first week of the month otherwise, I would like to calculate the sum of turnover of the current month.

Could you please HELP me.

@Anonymous May be best is to show prev month if day of the month is less than 7th of the month and then current month, coz week number can be spill over multiple months.

My Measure = 
IF ( DAY( TODAY() ) <= 7,
CALCULATE( 
[Sum of Turnover], 
PREVIOUSMONTH( 'Calendar'[Date] ),
Table[Flag] = "OK" 
),
CALCULATE( 
[Sum of Turnover], 
Table[Flag] = "OK" 
)
)
