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)

Hi Anonymous ,

Try the following 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]
                        = MAX ( rclms_qa[Year] ) - 1
            )
        )),
    CALCULATE ( COUNTA ( 'rclms_qa'[CONFORMITY] ), ALL ( 'rclms_qa') )
) * 100

(the picture (3-1)/14=14.29)

This measure, will automatically calculate the difference between the date in the column and the date before the 13 stages, and then divided by the total, I provide my PBIX, which has some of my thinking and verification steps, you can refer to, I hope it will be useful to you.

Best Regards

Dear v-luwang-msft

Thanks a lot - I'm really impressed by the work & formula.

I have one doubt regarding the calculation because if we are in P13 2020, 13 periods earlier, we should be in P1 2020 (and not P1 2019) -> no?

Thanks

Hello Lucien,
I'm sorry - I have another question. I was trying to make a graph/year:
We are in P08 2021 -> why it's stopped at P05?
Thanks

  Hi Anonymous ,
  
  Try to change ALL( 'Tablename') in measure you used to be ALLSELECTED('Tablename').
