Unique identifier with SharePoint

[Vitorino]

Hello friends, I have a list on the sharepoint where each item has to have a Unique identifier, I am using the function
-> Max (Table, Column) +1, but the error "Delegation warning is coming. The highlighted part of this formula may not work correctly on large data sets. The" Max "operation on this connector is not supported." and I saw that SharePoint is delegable.

My PowerApps is in Portuguese, but the error is what I mentioned above.

Max is not a delegable function in SharePoint.  You are limited to the functions shown in the link below.

Is there any way to create this accountant?

This function would work and also can be delegated in SharePoint.

First(Sort(Etiquetas, Identificador, Descending)).Identificador + 1
