    I would venture it is because your RANKX function doesn't have the column reference to rank the values by. Include a column reference after the table reference:

    RANKX ( MonthTable, MonthTable[...], CALCULATE ( AVERAGE ( Date[DayOfMonth] ) ),, ASC )

     

    See if that works.

     

    EDIT: you might also need an ALL or ALLSELECTED before the table expression, depending on the context you wish to calculate de Rank by:

    RANKX ( ALLSELECTED(MonthTable), MonthTable[...], CALCULATE ( AVERAGE ( Date[DayOfMonth] ) ),, ASC )

Hi Anonymous ,

 

Please make sure your table names are consistent, otherwise errors will occur. Change table name to either 'Date' or Date.
