Creating calculated column to understand - "Current Month", "Previous Month", and "Others"

[rahulmenon]

Hi All,

I need a help on the below.

I want to create a calculated column in my Power BI report which shows values as "Current Month", "Previous Month", and "Others", based on the Date column in the same table/report.

Current month should be the Max of month available in the date column. Hence not necessarily based on actual calendar dates. 

If that is not possible, I am okay to have two different column, one for "Current Month" which shows test "CM" for current month dates, and rest all "Others", and another column which shows "PM" for Previous month (CM-1) and all other values "Other".

Please can someone help me to achieve this?

@Greg_Deckler  thanks for your concern about this case. I tried to create a sample data myself based on the user's requirement and implemented the result. Here is my solution:

First, I created the following date table.

Then you can try the following dax:

Measure = 
VAR _max = CALCULATE(MONTH(MAX('Table'[Date])),FILTER(ALL('Table'),'Table'[Date]))
RETURN
IF(MONTH(SELECTEDVALUE('Table'[Date]))=_max,"current",IF(MONTH(SELECTEDVALUE('Table'[Date]))+1 = _max,"last","other"))

This is the result:

@rahulmenon , if this sample data is structurally different from the one you are using, please do not hesitate to mention it and I will modify it!

Best Regards,
