Circular Dependency

Hello Everyone, I have the following  calculated table : 

Previous_Days_Late_Lines =
VAR CurrentDate = StockMovements[Required_Date]
VAR PreviousDate = TRUNC(StockMovements[Previous_Date])
       
RETURN
CALCULATE(
DISTINCTCOUNT(StockMovements[Product_Code]),
FILTER(
ALL(StockMovements),
TRUNC(StockMovements[Required_Date]) = PreviousDate   && StockMovements[FinalisedDate] > StockMovements[Required_Date])),
 
 
previous date is also a calculated coloumn : 
Previous_Date = IF(
    WEEKDAY(StockMovements[Required_Date],2) =1,
    StockMovements[Required_Date]-3,
    StockMovements[Required_Date]-1)
 
 
The measure was updating well, but now it gives a "circular dependency error". Is there a way to get around this without creating a static previous date coloumn?

    Hello Khomotjo,

     

    Can you please try calculating the PreviousDate inline using a variable:

    Previous_Days_Late_Lines =
VAR CurrentDate = StockMovements[Required_Date]
VAR PreviousDate = 
    IF(
        WEEKDAY(CurrentDate, 2) = 1,
        CurrentDate - 3,
        CurrentDate - 1
    )
RETURN
CALCULATETABLE(
    DISTINCT(StockMovements[Product_Code]),
    FILTER(
        ALL(StockMovements),
        TRUNC(StockMovements[Required_Date]) = PreviousDate &&
        StockMovements[FinalisedDate] > StockMovements[Required_Date]
    )
)

      Thank you Sahir_Maharaj 
      Hi, Khomotjo 

      In my test, there is no circular dependency problem with your expression, can you provide some test data so that I can better analyze your requirements? You need to describe the results you expect based on the sample data you provide, so that I can try to write an expression for you that fits your business logic.
