    Hi yaya1974 ,

    The Table data is shown below:

     

    Try this.

    Avarage = 
VAR _a = [Date]
VAR _table1 = 
ADDCOLUMNS('Table',
"MonthNumber",SWITCH(TRUE(),
LEFT([Date],3) = "Jan",1,
LEFT([Date],3) = "Feb",2,
LEFT([Date],3) = "Mar",3,
LEFT([Date],3) = "Apr",4,
LEFT([Date],3) = "May",5,
LEFT([Date],3) = "Jun",6,
LEFT([Date],3) = "Jul",7,
LEFT([Date],3) = "Aug",8,
LEFT([Date],3) = "Sep",9,
LEFT([Date],3) = "Oct",10,
LEFT([Date],3) = "Nov",11,
LEFT([Date],3) = "Dec",12
)
)
VAR _table2 = ADDCOLUMNS(_table1,
"Rank",RIGHT([Date],2) * 100 + [MonthNumber])
VAR _table3 = ADDCOLUMNS(_table2,
"Begin",IF( [MonthNumber] >=1 && [MonthNumber] <=6,
(RIGHT([Date],2) - 1) * 100 + 5,
(RIGHT([Date],2) - 1) * 100 + 11),
"End",IF( [MonthNumber] >=1 && [MonthNumber] <=6,
(RIGHT([Date],2) - 1) * 100 + 10,
RIGHT([Date],2) * 100 + 4)
)
VAR _table4 = ADDCOLUMNS(_table3,"Average",AVERAGEX(FILTER(_table3,[Rank] >= EARLIER([Begin]) && [Rank] <= EARLIER([End])),[Input]))
RETURN MAXX(FILTER(_table4,[Date] = _a),[Average])

    Final output

Hi Ankur04 ,thanks for your quick reply, I will add more.

Hi yaya1974 ,

If I understand correctly, January to June 2024 are calculated as the average of November 2023 to April 2024.

The Table data is shown below:(The data type of the 'Date' column is Text)

Use the following DAX expression to create a column.

 

Avarage = 
VAR _a = [Date]
VAR _table1 = 
ADDCOLUMNS('Table',
"MonthNumber",SWITCH(TRUE(),
LEFT([Date],3) = "Jan",1,
LEFT([Date],3) = "Feb",2,
LEFT([Date],3) = "Mar",3,
LEFT([Date],3) = "Apr",4,
LEFT([Date],3) = "May",5,
LEFT([Date],3) = "Jun",6,
LEFT([Date],3) = "Jul",7,
LEFT([Date],3) = "Aug",8,
LEFT([Date],3) = "Sep",9,
LEFT([Date],3) = "Oct",10,
LEFT([Date],3) = "Nov",11,
LEFT([Date],3) = "Dec",12
)
)
VAR _table2 = ADDCOLUMNS(_table1,
"Rank",RIGHT([Date],2) * 100 + [MonthNumber])
VAR _table3 = ADDCOLUMNS(_table2,
"Begin",IF( [MonthNumber] >=1 && [MonthNumber] <=6,
(RIGHT([Date],2) - 1) * 100 + 11,
RIGHT([Date],2) * 100 + 5),
"End",IF( [MonthNumber] >=1 && [MonthNumber] <=6,
RIGHT([Date],2) * 100 + 4,
RIGHT([Date],2) * 100 + 10)
)
VAR _table4 = ADDCOLUMNS(_table3,"Average",AVERAGEX(FILTER(_table3,[Rank] >= EARLIER([Begin]) && [Rank] <= EARLIER([End])),[Value]))
RETURN MAXX(FILTER(_table4,[Date] = _a),[Average])

 

Final output   0.425 = (0.4375 + 0.4375 + 0.4125 + 0.4125 +0.4125 + 0.4375 ) / 6

    Hi Wenbin,  Thank you!   You Almost got it!   the formula works but it is just averaging the wrong data to get to the answer.  for example:

    Jan-24 through Jun-24 = .4543

    to get to that answer the average comes from May-23 through Oct-23

    So, the data is six months in the past (going back two months to start)   hope that makes sense?

    is there a way to edit formula so that can happen?
