    Hi, SummaL 

    I can reproduce the same error.

    I don't know what exactly causes this error, but after encapsulating the condition with ‘filter’, the code can run normally.

    IsCurrentWeek =
VAR currentrowweek = 'Calendar'[Fiscal_Week]
VAR iscurrentweek =
    CALCULATE (
        MIN ( 'Calendar'[Fiscal_Week] ),
        FILTER ( 'Calendar', 'Calendar'[DATE] = TODAY () )
    )
RETURN
    IF ( iscurrentweek = currentrowweek, "Yes", "No" )

SummaL , same name seems like an issue, try like

 

IsCurrentWeek =
var _currentrowweek = 'Calendar'[Fiscal_Week]
var _iscurrentweek = CALCULATE(MIN('Calendar'[Fiscal_Week]),'Calendar'[DATE]=TODAY())
return
if (_iscurrentweek=_currentrowweek, "Yes", "No")

    If renaming the variables doesn't sort it have a read of 

    https://www.sqlbi.com/articles/avoiding-circular-dependency-errors-in-dax/

     

    In summary when you use CALCULATE in the second calculated column it causes a context transition and moves all columns from the current row into the filter context. That includes the other calculated columns so they end up being circular.

     

    You need to add ALLEXCEPT into the calculate to reference just the column(s) you need to use.
