Offsetting Calculated Column Rows
Hi guys,
I'm having a bit of a dilemma with generating a Calculated Column in DAX, the goal is to calculate Cal_charge+Amt column from the Excel table above. As you can see, the data on that column is exactly the same numbers as Sum of chargeAmt except that it's offset by 2 months behind. I have no idea where to begin to be able to generate that new column and make the first 2 rows blank like that. I need that column in order to generate Cash Factor. I'm new to the Power BI and DAX world so I would appreciate the help.
Try this calculated column
Cal_charge+Amt = VAR temp = TOPN ( 2, FILTER ( Table3, [Month-Year] < EARLIER ( [Month-Year] ) ), [Month-Year], DESC ) VAR temp1 = TOPN ( 1, temp, [Month-Year], ASC ) RETURN IF ( COUNTROWS ( temp ) = 2, MINX ( temp1, [Sum of ChargeAmt] ) )When I use it with a sample table it works

Hi ccueto36,
Based on my test, I have tried what Zubair suggested, it could work on my side, and you could also refer to my step:
Sample data:
Create a calculated column:
Column 2 = var a=MONTH('Table3'[Month-Year])-2 return CALCULATE(SUM(Table3[Sum of ChargeAmt]),FILTER('Table3',MONTH('Table3'[Month-Year])=a))Result(Column1 is the Zubair's function):
You could also download the pbix to have a view, if it still could not work, could you please share the pbix if possible?

I'm getting a fully blank calculated column as a result every time I try it. If I take off the IF(COUNTROWS(temp1) = 2 condition, then it's not blank anymore, just random numbers that isn't the expected answer. On a side note, Table3 is the table name where all of the above columns are from?
