Hi Both, Thanks very much for your help. I tried to set SourceSchemaChangesAllowed to true for both the source feature service and the view layer but whilst the updating process appeared to work, the change didn't seem to apply.  Given the problem was the view layer, I ended up just deleting it, setting the unique property and then recreating the view.  I really should have thought that the view was getting in the way - it's not the first time it's caused me problems and is in fact the very reason I wanted to set the unique property in the first place. The source layer gets updated regularly and I used to just do a full update. The view layer now prevents this but I was advised that appending with a unique identifier should work instead. I originally published via zipped shapefile and the view is the output of a join. I wanted to display some descriptive popup text for each feature but the maximum string length of a shapefile was a constraint. I ended up just joining the polygons to a CSV file containing the text. Thanks again,  Richard ... View more

Thanks for looking into this Mike.  I've tried again but I'm afraid I don't know my way around the browser console so don't really know what i'm looking for. To my eyes, nothing changes when I try to set the unique property, but I'm almost certainly not looking in the correct place. Could you give me an idea of what I'm looking for and where? I'm using Chrome if that's important.  Richard ... View more

Hi Kelly, I'm having the same issue - the layer can be found here: https://swt.maps.arcgis.com/home/item.html?id=4d94870d0f184cb7809eb9be51edc024 and the field is SWT_Code.  All the values are unique and there are no blanks. When trying to mark the field as unique, I get the following error: "Validation failed: Field does not contain unique values. Remove duplicates and try again" Thanks, Richard ... View more
