Define Shifts Where Weekend/Weekday Shifts Involve Different Hours

[hickkich]

Hi, 

I am trying to create a column that determines if the event happened on a day or night shift.  Here is the column that I am trying to use to determine the shifts. 

A week day shift is 8a-5p

A week night shift is 5p-8a

A weekend day shift is 8a-8p

A weekend night shift is 8p-8a

Of note, I found a similar thread where a user was trying to do this with a similar date column.  When I used their switch formulaI received an error that the first 6, is unexpected.

A shift = Mon-Friday 06:00:00-14:00:00

B shift = Mon-Friday 14:00:00-22:00:00

C shift = Sun-Fri 22:00:00-06:00:00

D shift = Sat and Sun 06:00:00-18:00:00

Shift = SWITCH ( TRUE (), AND ( HOUR ( Table[EventTime] ) IN { 6, 7, 8, 9, 10, 11, 12, 13 }, WEEKDAY ( Table[EventTime] ) IN { 2, 3, 4, 5, 6 } ), "A", AND ( HOUR ( Table[EventTime] ) IN { 14, 15, 16, 17, 18, 19, 20, 21 }, WEEKDAY ( Table[EventTime] ) IN { 2, 3, 4, 5, 6 } ), "B", AND ( HOUR ( Table[EventTime] ) IN { 22, 23, 24, 1, 2, 3, 4, 5 }, WEEKDAY ( Table[EventTime] ) IN { 1, 2, 3, 4, 5, 6 } ), "C", AND ( HOUR ( Table[EventTime] ) IN { 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 }, WEEKDAY ( Table[EventTime] ) IN { 6, 7 } ), "D" )

Hi @hickkich 
Please refer to attached sample file with the proposed solution.

You need to create a shift table as per the screenshot. You need to edit the same to suit your requirement as you can see that some times return blank values which means that apparently I don't fully understand the timings of the different shifts. 

With the help of the shifts table, the shift calculated column will become a simple DAX formula.

Shift = 
MAXX ( 
    FILTER ( 
        Shifts,
        Shifts[Weekday Number] = WEEKDAY ( Data[CreationInstant], 2 )
            && TIMEVALUE ( Data[CreationInstant] ) >= Shifts[StartTime]
            && TIMEVALUE ( Data[CreationInstant] ) <= Shifts[EndTime]
    ),
    Shifts[Shift]
)

hi @hickkich 

try like:

Shift = 

VAR _h =HOUR( TableName[CreationInstant] ) 

VAR _d = WEEKDAY ( TableName[CreationInstant], 2 )

VAR _condition1 = _h>=8 && _h <=17

VAR _condition2 = _d IN {6, 7}

RETURN

SWITCH ( 

    TRUE (), 

    _condition1&&NOT _condition2, 

    "week day shift",

    NOT _condition1&&NOT _condition2, 

    "week night shift",

    _condition1&&_condition2, 

    "weekend day shift",

    "weekend night shift"

)
