    Hi Anonymous ,

    Sorry, it was an oversight on my part and I have adjusted the relevant measure😋:

    Percentage22 = 
DIVIDE (
    (CALCULATE (
        COUNTA ( 'rclms_qa'[CONFORMITY] ),
        FILTER (
            ALL(rclms_qa),
            rclms_qa[Period] = MAX ( rclms_qa[Period] )
                && rclms_qa[Year] = MAX ( rclms_qa[Year] )
        )
    )
        - CALCULATE (
            COUNTA ( 'rclms_qa'[CONFORMITY] ),
            FILTER (
                ALL(rclms_qa),
                rclms_qa[Period]
                    = IF (
                        INT ( VALUE ( RIGHT ( MAX ( rclms_qa[Period] ), 2 ) ) + 1 ) < 10
                            || INT ( VALUE ( RIGHT ( MAX ( rclms_qa[Period] ), 2 ) ) + 1 ) = 14,
                        "P" & "0"
                            & IF (
                                INT ( VALUE ( RIGHT ( MAX ( rclms_qa[Period] ), 2 ) ) + 1 ) = 14,
                                1,
                                INT ( VALUE ( RIGHT ( MAX ( rclms_qa[Period] ), 2 ) ) + 1 )
                            ),
                        "P"
                            & INT ( VALUE ( RIGHT ( MAX ( rclms_qa[Period] ), 2 ) ) + 1 )
                    )
                    && rclms_qa[Year]
                        =IF (
                        INT ( VALUE ( RIGHT ( MAX ( rclms_qa[Period] ), 2 ))) =13, MAX ( rclms_qa[Year] ), MAX ( rclms_qa[Year] ) - 1)
            )
        )),
    CALCULATE ( COUNTA ( 'rclms_qa'[CONFORMITY] ), ALL ( 'rclms_qa') )
) * 100
    YEARTEST = IF (
                        INT ( VALUE ( RIGHT ( MAX ( rclms_qa[Period] ), 2 ) )  )=13, MAX ( rclms_qa[Year] ), MAX ( rclms_qa[Year] ) - 1)

     

     

    Best Regards

Please provide sample data in usable format (not as a picture) and show the expected outcome.

Hello lbendlin 

Here is the table:

 

YearCONFORMITYPeriodFactories
2020OKP13RCA
2020OKP13RCA
2020OKP13RCA
2021OKP01RFT
2021WRNG_NOKP01RFT
2021OKP02RNI
2021OKP02RNI
2021OKP02RNI
2021OKP02RNI
2021OKP02RNI

 

So the Grade A (control OK) will be calculated based on the formula above - then I need to make the % Grade A difference (P2-P1 2021) + (P1 2021-P13 2020).

Outcome would be + or - x %.

 

Thanks for your help - and let me know if not clear.
