Hi @Anonymous ,
****UPDATE - I was preparing the below while you were corresponding with @Anonymous - both options should be considered ****
On new records, one approach would be to have a true/false flag in a hidden SharePoint field and either Patch or Default it to true (hide it on the form) in Power Apps. You could then have a warning label on the screen with the Visible property
!ThisItem.YourFlagFieldName
so it would not be visible if the field was true.
Updates are a bit more problematic however one approach might be to have a shadow date field and write Now() to it as above every time a change is made. Then the Visible on the label would be
Not(
Text(
ThisItem.YourShadowDate,ShortDate
) = Text(
ThisItem.Modified,ShortDate
)
)
There will be a Delegation issues on both the Not and the Date comparison. As I could not avoid the Date, I left them both in.
Further on your issue of amendment by other means, I have several SharePoint reference lists in a sub-site that is nowhere in the site navigation display, so the user would have to know the sub-site and list names to find them.
