Avoiding delegation warning in collection

[JamesSnaps]

Thanks to some helpful posts on this forum, I'm using a function to collect a range of dates in a collection. I'm also looking to add a column to the code, that uses LookUp on a SharePoint list to verify dates. The code all works, but I get a delegation warning on the checkDate=DateAdd(weekStart, Value, Days) part. If I change 'Value' to a static number, this warning goes away. Is there any way to avoid this delegation warning at all, whilst using the current Value?

Or is the warning in this instance not a big deal and therefore I shouldn't worry about it?

ClearCollect(
    DateRange,
    AddColumns(
        FirstN(
            [0,1,2,3,4],
            DateDiff(weekStart, DateAdd(Today(),1-Weekday(Today(),StartOfWeek.Monday)+4,Days), Days) + 1),
        "Day",
            "Day " & (Value + 1),
        "Date",
            DateAdd(weekStart, Value, Days),
            "complete",If(IsBlank(LookUp(sfbbLogs,checkDate=DateAdd(weekStart, Value, Days))),false,true)
    )
)

Hi @JamesSnaps ,
Date queries are not Delegable, not matter how you "wrap" them. I have a workaround in this section of my blog on Delegation, although it may not be suitable for you.

Hi @WarrenBelz , thanks for the reply. Why would the function appear as fine (no delegation warning) when I change 'value' to a static number, e.g. 1. Is that not still a date query? It would appear that it's the use of 'Value' that is causing the warning, so just curious.

ClearCollect(
    DateRange,
    AddColumns(
        FirstN(
            [0,1,2,3,4],
            DateDiff(weekStart, DateAdd(Today(),1-Weekday(Today(),StartOfWeek.Monday)+4,Days), Days) + 1),
        "Day",
            "Day " & (Value + 1),
        "Date",
            DateAdd(weekStart, Value, Days),
            "complete",If(IsBlank(LookUp(sfbbLogs,checkDate=DateAdd(weekStart, 1, Days) && nurseryID=varNursery.ID)),false,true)
    )
)

I can also change checkDate=DateAdd(weekStart, Value, Days) to just be checkDate=Today() and that also works fine, no warning. But using Value anywhere in the formula results in a delegation warning

Hi @JamesSnaps ,

I am not sure - I have not tried that one myself. Beware however that there are a number of things you can do in Power Apps that are "hidden" delegation limitations (the With() statement is one of them), but I have never been able to filter large data sets on date fields.

I think so Warren, I used the information to basically set up a different workflow that wouldn't suffer from being non-delegable, so thanks for the clarification.
