Fresh out of ideas after a measure stopped working

[noodles281]

I have a table that records daily transactions so we like to see how many there are each day. We had a simple line chart comparing daily transatctions against the last three years so for example you could see 01-Aug-2016 compared to 01-Aug-2017 and 01-Aug-2018, the chart would show the full calendar month (more for simplicity than for any specific reason in theory last 30 -35 days would be more appropriate)

I have not been able to get SAMEPERIODLASTYEAR to work or PARALLELPERIOD or DATEADD, it's got to the point where I'm convinced it's a simple mistake I'm making but I'm fresh out of ideas.

WIP Y-1 =
CALCULATE (
    COUNTROWS ( fWIP ),
    FILTER (
        fWIP,
        fWIP[InApproval] = FALSE ()
            && fWIP[capcreated] = FALSE ()
            && fWIP[isBUS] = FALSE ()
            && fWIP[isLeaver] = FALSE ()
    ),
    USERELATIONSHIP( dDates[Date] , fWIP[stamp] ),
    SAMEPERIODLASTYEAR( dDates[Date] )

)

In the past I did get it to work using some horrific DAX, but that has stopped working

WIP Y-1 Test2 =
CALCULATE (
    COUNTROWS ( fWIP ),
    FILTER (
        fWIP,
        fWIP[InApproval] = FALSE ()
            && fWIP[capcreated] = FALSE ()
            && fWIP[isBUS] = FALSE ()
            && fWIP[isLeaver] = FALSE ()
    ),
    ALL ( dDates ),
    DATESBETWEEN (
        dDates[Date],
        CALCULATE ( MIN ( DDates[Date] ), dDates[monthdrift] = -12 ),
        CALCULATE ( MAX ( DDates[Date] ), DDates[monthdrift] = -12 )
    )
)

I managed to solve this just now. I went back to basics and fixed it, but I don't understand why it works as the visual filters should have stopped this from working, I was expecting to have to set a current month version of the measure up to be able to remove the current month filter from the visual (dDates[Monthdrift] = 0)

The measures  that worked are

This Year =
CALCULATE(
COUNTROWS ( fWIP ),
FILTER (
fWIP,
fWIP[InApproval] = FALSE ()
&& fWIP[capcreated] = FALSE ()
&& fWIP[isBUS] = FALSE ()
&& fWIP[isLeaver] = FALSE ()
),
)

Last Year = 
CALCULATE(
COUNTROWS ( fWIP ),
FILTER (
fWIP,
fWIP[InApproval] = FALSE ()
&& fWIP[capcreated] = FALSE ()
&& fWIP[isBUS] = FALSE ()
&& fWIP[isLeaver] = FALSE ()
),

ddates[Monthdrift] = -12

)

2 years ago = 
CALCULATE(
COUNTROWS ( fWIP ),
FILTER (
fWIP,
fWIP[InApproval] = FALSE ()
&& fWIP[capcreated] = FALSE ()
&& fWIP[isBUS] = FALSE ()
&& fWIP[isLeaver] = FALSE ()
),

dDates[Monthdrift] = -24

)

Hi @noodles281,

I tried to made a sample based on your description, but failed, Could you please share your pbix to me so that I can help with it?

Hello Frank,

Thanks for getting back to me, I'm afraid I cannot share the file.
