Calculating MTD

[Anonymous]

How can I make a DAX formula MTD for only full months. So March has not ended yet so it has to be till Februari with this formula : 

DPA M-3_CY = if('KPI''s 2021'[input DPA m-3] = 0, " ", ((1-SUM('KPI''s 2021'[Abs Diff M - 3])/sum('KPI''s 2021'[Order Quantity]))*100))

Hi @Anonymous 

Can you post sample data as text and expected output?
Not enough information to go on;

please see this post regarding How to Get Your Question Answered Quickly:

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
4. Relation between your tables

Appreciate your Kudos!!

I read your advice and hopefully this will clarify a bit.

MAR 2021	3	2021	March	2021	40	200

When it is for instance half March it should calculate only the sum of Jan/Feb M-3 = 667 divide by sum Jan/Feb order quantity = 2313 = expected output = 29%

Hi, @Anonymous 

If you have a seperated calendar table without any relationship, you can try the formula as below:

Result = 
VAR _today =
    SELECTEDVALUE ( 'Calendar table'[Date] )
VAR a =
    CALCULATE (
        SUM ( 'Table'[Abs Diff M - 3] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Cal. year / month.Cal. year / month Level 01]
                < STARTOFMONTH ( 'Calendar table'[Date] )
        )
    )
VAR b =
    CALCULATE (
        SUM ( 'Table'[Order Quantity] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Cal. year / month.Cal. year / month Level 01]
                < STARTOFMONTH ( 'Calendar table'[Date] )
        )
    )
RETURN
    a / b
