Month Over Month Change (Exclude First Month and Month After)

Hi Power BI Community,

 

I am running into an issue using month over month change (not % change but actual difference). My data consists of month balances until the current month where it is the previous days balance. For Example, I have December 2017 to August 2019 (mid month), when I use the canned calculation for MoM, it shows December of 2017 as a full increase instead of dropping this month, and adds September 2019 showing a full decrease because there is no data. All months inbetween function correctly except the bookend months. Below is the canned formula, thanks for your help!

 

 

IF(
    ISFILTERED('query1'[Month End]),
    ERROR("Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column."),
    VAR __PREV_MONTH = CALCULATE([weighted measure], DATEADD('query1'[Month End].[Date], -1, MONTH))
    RETURN
        DIVIDE([weighted measure] - __PREV_MONTH, __PREV_MONTH)

    Hi Anonymous,

     

    You can use the following Measure to count actual difference Month Over Month, but do not remember to close the “show items with no data”.

     

    Measure = 
VAR pre =
    CALCULATE (
        [weighted measure],
        DATEADD ( 'query2'[Month End].[Date], -1, MONTH )
    )
VAR thisMonth =
    CALCULATE ( [Weighted Measure] )
VAR d =
    SELECTEDVALUE ( query2[Month End] )
VAR ma =
    MAXX ( ALL ( query2 ), [Month End] )
VAR mi =
    MINX ( ALL ( query2 ), query2[Month End] )
RETURN
    IF ( d > mi && d < ma, thisMonth - pre, BLANK () )

     

     

    BTW, pbix as attached.
