Hi,
I've got a query set to calculate the number of working days based on two dates;
= (InitialDate as date, FinalDate as date ) as number =>
let
DaysBetweenDates = Duration.Days(FinalDate-InitialDate),
DaysList = List.Dates(List.Min({InitialDate,FinalDate}),Number.Abs(DaysBetweenDates)+1, Duration.From(1)),
WeekDaysList = List.Select(DaysList, each (Date.DayOfWeek(_, Day.Monday) < 5) ),
WorkingDays = (if DaysBetweenDates < 0 then -1 else 1) * List.Count(WeekDaysList)
in
WorkingDays
however, I don't always have dates available in these columns, and so where this is the case, I get an error. Can anyone suggest a way to prevent me getting these errors flagged? I'd be fine with just Null values in these instances, but can't work out how to get these to show instead of the error.
Regards

Hi, @ChrisBroome , a most straightforward way is to enclose the function invocation into a try ... otherwise to catch errors like this,
Invoking = try Query1(#date(2020, 11, 10), null) otherwise ""

Hi @ChrisBroome
Try this:
(InitialDate as any, FinalDate as any ) as any =>
if (InitialDate=null or FinalDate=null) then null else
let
DaysBetweenDates = Duration.Days(FinalDate-InitialDate),
DaysList = List.Dates(List.Min({InitialDate,FinalDate}),Number.Abs(DaysBetweenDates)+1, Duration.From(1)),
WeekDaysList = List.Select(DaysList, each (Date.DayOfWeek(_, Day.Monday) < 5) ),
WorkingDays = (if DaysBetweenDates < 0 then -1 else 1) * List.Count(WeekDaysList)
in
WorkingDays
