Delegation error

[bsimon]

Hi All,

I have a gallery that reads from a SP list. I am using the sort command below on the galleries items property 

The SP list has only 80 items in it. I am having an issue with this line using the app checker

TextSearchBox1.Text in Title I have also tried using Text(title). Title is is the name of the SP column

Any suggestions ? Thanks

Sort
(If
(IsBlank(TextSearchBox1.Text), 'Software Catalog',Filter('Software Catalog', TextSearchBox1.Text in Title) ),
Title,
If(SortDescending1,
SortOrder.Descending,
SortOrder.Ascending)
)

The In operator is not delegable, so you will see a warning message for that.

It should ONLY be a warning.  This is not an error in your formula.

It is telling you that if your datasource grows beyond the maximum number of records allowed (500 by default, expandable to 2000), then you might get incomplete results.

If your list is only 80 items and you do not expect it to grow beyond 2000, then you can ignore this warning.

I hope this is helpful for you.

Hi @bsimon ,

Delegation is just a warning not error.

Since your items number is smaller than 2000, you do not need to worry about it.

Only if your record is larger than 2000, the delegation warning means that your app may not perform well.

The appearence of delegation warning is because that you use undelegable functions.

I suggest you change your non-delegable limit to 2000, then there's no need to worry about delegation warning when your record is smaller than 2000.

File->App settings->Advanced settings

What's more, here's a doc about deleagtion for your reference:

Agree with what @RandyHayes wrote here - its a warning and if you don't foresee hitting 2000+ items then I would leave the formula as-is and mark his solution as the answer.

If you do think you will end up with over 2000 items, then you could change your 'in' to a StartsWith - which is not as flexible but it will allow you to delegate the search 🙂

Sort(
        If(
            IsBlank(TextSearchBox1.Text),
                'Software Catalog',
                Filter('Software Catalog', StartsWith(Title, TextSearchBox1.Text)
        ),
        Title,
        If(
           SortDescending1,
           SortOrder.Descending,
           SortOrder.Ascending
        )
)
