Unique ID with Spinner?

I built a survey based on an existing feature service that has a unique Unit_ID column (integer). The field crews are going to review existing features and also collect new ones and they will need to assign a unique Unit_ID number to each of the new collected features.

Is there a way to show the largest Unit_ID value and set the field appearance to spinner?

This way the field crews will increment the largest value by 1 each time they are adding a new feature, and they won’t need to remember what was the last Unit ID they used.

Hi Ayelet,

It may be possible to query the feature service and retrieve the largest value via a custom JavaScript function (in beta).
