PYTD Function Issue

Hi,Anonymous 

1.First I have created the following table and the column names and data are the data you have given:

2. Below are the measure I've created for your needs:

MEASURE = 
VAR cdate =
    CALCULATE (
        MAX ( 'Combined Table'[QR Date] ),
        FILTER (
            ALLSELECTED ( 'Combined Table' ),
            'Combined Table'[QR Date].[Year] = MAX ( 'Combined Table'[QR Date].[Year] )
        )
    )
RETURN
    CALCULATE (
        SUM ( 'Combined Table'[Quota Credit] ),
        FILTER (
            'Combined Table',
            'Combined Table'[QR Date].[Year]
                = YEAR ( cdate ) - 1
                && 'Combined Table'[QR Date] <= EDATE ( cdate, -12 )
        )
    )

3.Here's my final result, which I hope meets your requirements.

hi Anonymous ,

TOTALYTD and SAMEPERIODLASTYEAR are time intelligence functions, to use them, you need a dedicated calendar table. Without the calendar table, try a measure like:

PYTD =
VAR _todaylastyear = EDATE(MAX('Combined Table'[QR Date]), -12)
VAR _result = 
CALCULATE(
    SUM('Combined Table'[Quota Credit]),
    FILTER(
        ALL('Combined Table'[QR Date]),
        'Combined Table'[QR Date])<_todaylastyear
            &&YEAR('Combined Table'[QR Date])) = YEAR(_todaylastyear)
    )
)
RETURN _result
