Process = UNLOAD-LOAD*1440

 

We are a 24/7 operation...M shift = 7am-7pm and E shift =7pm-7am. How can I assign the correct number of minutes to each shift? Specifically, production that crosses midnight has me baffled.

 

Any help is greatly appreciated!

Hi @robandemmy ,

 

I forgot to modifiy something in the E shift calculation, it has been changed now. Please try:

M shift = 
VAR _a =
    DATE ( YEAR ( [LOADTIME] ), MONTH ( [LOADTIME] ), DAY ( [LOADTIME] ) )
        + TIME ( 7, 0, 0 )
VAR _b =
    DATE ( YEAR ( [LOADTIME] ), MONTH ( [LOADTIME] ), DAY ( [LOADTIME] ) )
        + TIME ( 19, 0, 0 )
VAR _c =
    DATE ( YEAR ( [UNLOADTIME] ), MONTH ( [UNLOADTIME] ), DAY ( [UNLOADTIME] ) )
        + TIME ( 7, 0, 0 )
VAR _sameday =
    SWITCH (
        TRUE (),
        [LOADTIME] < _a
            && [UNLOADTIME] < _b, DATEDIFF ( _a, [UNLOADTIME], MINUTE ),
        [LOADTIME] < _a
            && [UNLOADTIME] >= _b, DATEDIFF ( _a, _b, MINUTE ),
        [LOADTIME] >= _a
            && [UNLOADTIME] < _b, DATEDIFF ( [LOADTIME], [UNLOADTIME], MINUTE ),
        [LOADTIME] >= _a

        [LOADTIME] >= _b
            && [UNLOADTIME] >= _b, 0
    )

    )
RETURN
    IF ( _a = _c, _sameday, _diffday )

Thanks so much!! It's close but I am getting a few values that aren't coming back correct...looks like units that cross midnight:

robandemmy_0-1662639231709.png

I added a total time column as valiodation and am getting negative or incorrect large values when units cross over midnight.

Thanks for the reply...that's a partial solution. What I need to be able to do is assign the minutes to M and E shifts in a 7-7 operation...for example, if a unit loads at 5pm and unloads at 10pm, then M shift gets 120 minutes and E shift gets 180 minutes. That is one of the more simple examples...units that load at 6pm and unload at 2am for instance. M shift would get 60 minutes and E shift 420 minutes. Crossing midnight adds another level of complexity

@robandemmy,

 

In Power Query, try this expression in a custom column:

 

Duration.TotalMinutes([UNLOADTIME] - [LOADTIME])
