Updating registered view field alias and domains in Data Design Fields
This is actually two ideas but closely related so thought I would bundle them together.
In ArcCatalog it was possible to set the field alias and apply domains in a single interface, in the feature class properties:
I have just noticed in Pro's equivalent Data Design=>Fields that this function has been removed:
Notice though that Pro still displays these alias and domain settings, so not sure why this wouldn't be supported in data design?
Pro's Alter Field and Assign Domain To Field tools can alter registered views field alias and domains.
So my idea is, please add the ability to alter the field alias and domain for registered views using the Field Data Design form. Pro supports registered view field alias and domains so it makes sense to me to edit them here.
Oracle 18c 10.7.1 EGDB
Like you said, with a registered database view, I was able to apply a domain and an alias to a field using ArcCatalog 10.7.1 > Properties:
The domain and alias work as expected in the attribute table in both ArcMap 10.7.1 and ArcGIS Pro 2.9.5.
I submitted a couple of Esri Support cases:
Esri Case #03701138 Database view (registered with the geodatabase) — Can change field alias via Alter Field, but not via Fields View [ArcGIS Pro 2.9.5]
New: BUG-000170076 - Unable to alter the Alias of a field for a registered View via the Fields menu in ArcGIS Pro
Esri Case #03701213 Database view (registered with the geodatabase) — Can set field domain using ArcCatalog, but not ArcGIS Pro [ArcGIS Pro 2.9.5]
Existing/closed; working as designed: BUG-000135931 - When changing the domain assignment on a database view, the table is shown as read-only and does not allow the change.
Explanation - Views are read-only. Assigning domains to fields is supported using the Assign Domain To Field geoprocessing tool. Displaying a mixed state in the fields view of editable and non-editable properties is not in the current product plan.
