My leave request template Balance Add Selection checkbox for Half day & Full day Calculate

[Erng2]

On the SelectDate Screen I would like to add a button control (Checkbox) to allow staff to apply for either full day(s) or half days AM or PM.
I would need the calculation for requested days to be applied for the choice selected, 

Please see Attached file.

Hi @Erng2 

You could make your calculation based on which checkbox is selected. If the whole day, just calculate the difference in days and if it's half a day just make the same calculation and divide by 2. Of course add 1 to base calculation because the first day should be counted as a day as well.

If(
  FullDay.Value,
  DateDiff( DateFrom.SelectedDate, DateTo.SelectedDate, Days) + 1
  Morning.Value || Afternoon.Value,
  (DateDiff( DateFrom.SelectedDate, DateTo.SelectedDate, Days) + 1) / 2
)

 This of course does not yet take into account weekends and holidays. For that look to next article: https://powerapps.microsoft.com/es-es/blog/excluding-weekends-and-holidays-in-date-differences-in-po...

Hope this helps!

Hi @Erng2 

I forgot that if you were to take vacation over a longer period, but that you can start in the afternoon meaning only the first day should be half but not the rest. It really depends on how the logic should be. 

If I look in your attached file you have next case:

• Start date in afternoon on 6/24/2020 - 0.5 days
• Full day on 6/25/2020 - 1 day
• Full day on 6/26/2020 - 1 day

So total is 2.5 days right?

I simplified the calculation to next and explanation below with your case between the ( ) :

DateDiff( DateFrom.SelectedDate, DateTo.SelectedDate, Days) + if(Afternoon.Value, 0.5, 1) + If(Morning.Value, -0.5)

1. First we get the date difference (difference in days from 6/24 to 6/26 is 2 days)
2. Then we see if the period starts from morning or in the afternoon (afternoon - 0.5 days). Since date difference doesn't add up the first day because it only calculates the difference, you must add up 1 day (difference in days from 6/24 to 6/24 is 0 days, but should still counted as a vacation day), but if we only start in the afternoon only 0.5 days have to be add up. Thus we check if Afternoon is checked, and if so +0.5 days and else +1 day
3. Then we check whether the period stops at the end of the day or in the middle of the day. So for the day is counted as a whole day, so if Morning is check it means that you have to subtract 0.5 days from the total. If not, then nothing should be added.  

I left out the Fullday checkbox because this way we calculate the total based on full days and add or subtract according morning or afternoon. Then to make it clear you could still add validation to check if fullday nonetheless is checked, although it's not used.

I hope this helps better.

Hi @SkiDK ,
Thank you for the formula. After that, I followed the formula from you and I'm sorry to bother you again. I can't edit that formula and I need more than 1 option ( Mulitple Selected checkbox) as attached.

formula >> 
If(Fullday_2.Value,RoundDown(DateDiff(LeaveStartDatePicker_3.SelectedDate, LeaveEndDatePicker_3.SelectedDate, Days) / 7, 0) * 5 + Mod(6 + Weekday(LeaveEndDatePicker_3.SelectedDate) - Weekday(LeaveStartDatePicker_3.SelectedDate), 5),DateDiff( LeaveStartDatePicker_3.SelectedDate, LeaveEndDatePicker_3.SelectedDate, Days) + If(AM_1.Value,0.5,1) + If(PM_1.Value,-0.5) -CountIf(HolidaysCollection, StartDate >= LeaveStartDatePicker_3.SelectedDate, StartDate <= LeaveEndDatePicker_3.SelectedDate)) & " Days" 

This formula I made it, but I'm not sure the formula is correct or not.?

I don't know where I set formula ?

Hi @Erng2 

I made a quick replica of your case.

It works for me with next code. 

Label:

If(
    Fullday_2.Value,
    RoundDown(DateDiff(LeaveStartDatePicker_3.SelectedDate, LeaveEndDatePicker_3.SelectedDate, Days) / 7, 0) * 5 +
    Mod(5 + Weekday(LeaveEndDatePicker_3.SelectedDate) - Weekday(LeaveStartDatePicker_3.SelectedDate), 5)
    + If(AM_1.Value,0.5,1)
    + If(PM_1.Value,-0.5)
    - CountIf(HolidaysCollection,Date>=LeaveStartDatePicker_3.SelectedDate,Date<=LeaveEndDatePicker_3.SelectedDate)
,
    AM_1.Value || PM_1.Value,
    0.5
)
& " Days"

Of course you should check if Fullday was not checked, to see whether a half a day is to be counter for AM or PM.

And if you want to save the amount of days to a variable:

If(
    Fullday_2.Value,
    Set(vDaysLeave,
        RoundDown(DateDiff(LeaveStartDatePicker_3.SelectedDate, LeaveEndDatePicker_3.SelectedDate, Days) / 7, 0) * 5 +
        Mod(5 + Weekday(LeaveEndDatePicker_3.SelectedDate) - Weekday(LeaveStartDatePicker_3.SelectedDate), 5)
        + If(AM_1.Value,0.5,1)
        + If(PM_1.Value,-0.5)
        - CountIf(HolidaysCollection,Date>=LeaveStartDatePicker_3.SelectedDate,Date<=LeaveEndDatePicker_3.SelectedDate)
    )
,
    AM_1.Value || PM_1.Value,
    Set(vDaysLeave,
        0.5
    )
)

Make sure that in your HolidaysCollection the date is set as a date and not a string. Made a quick test list like this:

ClearCollect(HolidaysCollection,{Name: "hol1", Date: DateValue("2020-07-20")}, {Name: "hol2", Date: DateValue("2020-07-22")})

 Hope this helps!

Hi @SkiDK  Thank you for The Formula,  And I learned More about for Power apps and Formula ,

Other than that, can I bring information from the Checkbox to set up in the system? leave request template  How to ?

This formula I made it, but I'm not sure the formula is correct or not.?

Set Variables >> _requestedDays ? 

Output Example : leave Balance  for Vacation 10 days - I used 1.5 days  =  Total 8.5 days 

Thank you ,

 This formula, I put it on But I'm not sure if the formula is correct or not?

Set Variables >> _requestedDays ? 

Output Example : leave Balance  for Vacation 10 days - I used 1.5 days  =  Total 8.5 days  

How to Update or Patch  the system to Data.xlsx & leave request template  ?

This is exactly what i'm trying to do - did you find a solution and how/where to add those check boxes on the LeaveStartDatePicker?

[Anonymous]

Did anyone find a resolve for this? I've used the template and it's working perfectly but the ability to book a half day is required.

I've tried the formulas in the thread above and the one where a variable is created "sort of" works but it is not consistent.
