Create Calculated Column for Relative Month

[bensiqc]

I'm having trouble building out a calculated column that essentially uses a nested if statement to determine whether a period is within the current complete month (last month), the previous complete month (two months ago), or anything else ("Other").

Relative Complete Month = 
if(and(BillingSummary_0000_V70[Accounting Period Month Number] = MONTH(today()-1),BillingSummary_0000_V70[Accounting Period Year] = YEAR(today())),"Current Complete Month",if(and(BillingSummary_0000_V70[Accounting Period Month Number] = MONTH(today()-2),BillingSummary_0000_V70[Accounting Period Year] = YEAR(today())),"Prior Complete Month","Other"))

When I use the above, everything appears under the month of May or "Other". I'd expect data for the "Current Complete Month" to be April and "Prior Complete Month" to be March.

FYI, I have an accounting period column in the data which is just a date. Accounting Period Year is a number, Accounting Period Month Number is also a number.

I have some limitations with being able to link to any other data sources. I realize a date table would simplify this but I don't think it should be necessary. Just not sure why I can't get this formula working.

pls try this

Relative Complete Month = 
   VAR _toDay = TODAY()
   VAR _Last1month =  EOMONTH(_toDay,-1)
   VAR _Last2month =  EOMONTH(_toDay,-2)
RETURN
SWITCH( TRUE(),
      EOMONTH (BillingSummary_0000_V70[Accounting Period Date],0) = _Last1month , "Current Complete Month",
   
      EOMONTH (BillingSummary_0000_V70[Accounting Period Date],0) = _Last2month , "Prior Complete Month",

"Other" )
