Calculating the total number of Vehicle Service Days that are on Public Holidays

[CloudMonkey]

Hello,

I have uploaded my pbix file at https://we.tl/t-O7u7D4I8i5 

I have 3 unlinked tables (sorry it's not possible to link the tables for other reasons, I don't have control of that unfortunately):

 - Calendar (months)

 - Public Holidays

 - List of vehicles servicings with service dates

For each Calendar month, please can you tell me how to create a calculated measure to return the total number of vehicle service days that were public holidays? (it can't be a calculate column because I need to filter by other categories later on)

This is where I got to but I have to confess I am stuggling without the table relationships (the answer should be 0 in November, 6 in December (3 cars each being serviced on both 25th and 26th December), 0 in January)

Thank you for any help,

CM

Hi @CloudMonkey ,

I think you'd better have holiday data for each year, so I replace 2021 with 2020 year.

Then I create the following measures:

Measure = 
COUNTROWS(
    FILTER(
        'Vehicles Being Serviced',
        'Vehicles Being Serviced'[Date Taken Off Road] < MAX('Public Holidays'[Date])
        && 'Vehicles Being Serviced'[Date Returned] >= MAX('Public Holidays'[Date])
    )
)

Number of Vehicle Service Days that are Public Holidays = 
VAR FirstDayOfMonth = min('Calendar (Months)'[Month Start Date])
VAR FirstDayOfNextMonth = edate(FirstDayOfMonth,1)

RETURN
CALCULATE(
    SUMX( ALLSELECTED('Public Holidays'[Date]), [Measure] ), 
    FILTER(
        'Public Holidays',
        'Public Holidays'[Public Holiday Flag] =1 
        && 'Public Holidays'[Date] < FirstDayOfNextMonth
        && 'Public Holidays'[Date] >= FirstDayOfMonth
    )
)

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

@CloudMonkey , My idea would be to create a new column in the calendar to have flag public holidays.

We can join calendar and vehicles  on date and service date(without time)

Then we can have

calculate(countrows(vehicles), filter(Calendar, Calendar[Holiday] =1))

check if needed

refer 4 ways to copy data from one table to another

Thanks @amitchandak but as I say I'm not allowed to combined the tables, is there another way? Thanks

@CloudMonkey , Assume calendar is going to control the date

Try a measure like

new measure =
VAR _min = MINX( allselected('Calendar') , 'Calendar'[Date] )
VAR _max = MAXX(allselected('Calendar') , 'Calendar'[Date] )
var _tab = filter('Public Holidays', 'Public Holidays'[Date] >= _min && 'Public Holidays'[Date] <= _max && 'Public Holidays'[Holiday] =1)
return
calculate(countrows(vehicles), filter(vehicles, vehicles[date] in _tab))
