1. I have a point layer created from a view table (Latitude / Longitude). I can see the layer when symbolised as a single symbol, or graduated symbols (quantities) when the co-ordinate reference system is GCS_WGS_1984. However, when I use a projected co-ordinate system I cannot see the layer anymore.
2. If the map is published using the GCS_WGS_1984 co-ordinate system, I cannot see the graduated symbolised layers when the the mapservice is accessed through ArcGIS online. However, if I access the same layers as individual feature layers, it is visible.
ArcGIS Server 10.31
You should use Project (Data Management) tool to reproject the feature class from GCS to PCS [DO NOT use Define Projection or make changes from ArcCatalog > Feature Class Properties].
Try overwriting the corresponding Map Service while publishing in ArcGIS Online.
Jayanta, as I mentioned, this is view table (data changes frequently) so can't use as a feature class.
It worked in the past, but not sure why this is not supported now.
Can you provide a little more information on how your view was created...
What type of workgroup/enterprise database are you accessing information from (SQL Server, Oracle, other)? Is the view created, by you or a database administrator?
