Backwards calculation of remaining production order hours

Hi

I'm doing some productions planning, and i need show how many hours of production is planned for each day.

 

Example Production 001108 is budgeted with 100 hours and needs to be done at 24-06-2019, as seen from the left table.  The right table indicates, that 53,8 hours have already been clocked. So i need to spread out 46,2 hours over (46,2/7,4) = 7 days, aka. 7,4; 7,4; 7,4; 7,4; 7,4; 7,4, 1,8

Both tables are already connected to a common lookup table for a calender and for a production order

Re: Backwards calculation of remaining production order hours

Hi, @Nij 

 

I have created a report by you specs and the sample data you have provided. Based on the sample data I have created a few 1-to-1 relationships. If this is not how your data is, you would have to make som changes in some of the calculated columns. It is a bit messy to skip weekends, so some more testing with more data should probably be done. But that I leave to you 🙂

hours =
VAR weekendays =
    CALCULATE (
        SUM ( dates[IsWeekend] );
        FILTER (
            ALL ( dates );
            dates[Date]
                > MIN ( 'Production Orders'[EndDate] )
                    - MIN ( 'Production Orders'[Number of days left] )
                && dates[Date] <= MIN ( 'Production Orders'[EndDate] )
        )
    )
VAR startDateIsWeekend1 =
    IF (
        COUNTROWS (
            FILTER (
                ALL ( dates );
                dates[Date]
                    = MIN ( 'Production Orders'[EndDate] )
                        - MIN ( 'Production Orders'[Number of days left] ) - weekendays
                    && dates[IsWeekend] = 1
            )
        ) > 0;
        1;
        BLANK ()
    )
VAR startDateIsWeekend2 =
    IF (
        COUNTROWS (
            FILTER (
                ALL ( dates );
                dates[Date]
                    = MIN ( 'Production Orders'[EndDate] )
                        - MIN ( 'Production Orders'[Number of days left] ) - weekendays - 1
                    && dates[IsWeekend] = 1
            )
        ) > 0;
        1;
        BLANK ()
    )
        + IF ( ISBLANK ( startDateIsWeekend1 ); 1; 0 )
RETURN
    SWITCH (
        TRUE ();
        MIN ( dates[Date] )
            > MIN ( 'Production Orders'[EndDate] )
                - MIN ( 'Production Orders'[Number of days left] ) - weekendays - startDateIsWeekend1
            && MIN ( dates[Date] ) <= MIN ( 'Production Orders'[EndDate] ); 7,4;
        MIN ( dates[Date] )
            = MIN ( 'Production Orders'[EndDate] )
                - MIN ( 'Production Orders'[Number of days left] ) - weekendays - startDateIsWeekend1 - startDateIsWeekend2; SUM ( [Number of hours left] );
        BLANK ()
    )

cheers,
