Adding fields to Raster attribute tables

[RobertoRossi]

It seems is no longer possible (it was in ArcMap) to Add field to Raster Attribute tables, except through the Add Field geoprocessing tool.

The Add field button in the table window is inactive and it shows the message "This command is currently unavailable. The project has unsaved edits or the table or its schema is read only".

My opinion is that in ArcGIS Pro ArcGIS raster table schema is inactive by default.

Can anyone confirm (or deny) this?

I'm using ArcGIS Pro 2.8 and it's the same in 2.9

Thanks DanPatterson,

integer raster, it works from the toolbox, not the table

The same for me

Build raster attribute table

Go to Fields View

Add field

The same for me.

So, recapping:

1. If you try to add a field straight from the Table view: it doesn't work
2. If you try to add a field from the Field view: it works only if you have previously built the Raster Attribute Table with the omonime geoprocessing tool
3. you can always Add field via the Add Field Geoprocessing tool (also without building the Raster Attribute Table with the geoprocessing tool)

without re-reading and re-checking everything, that is what I think I confirmed.

The probable reason is that the "shortcut" has limitations that only the simplest of cases permits its use and that the shortcut is not a full-fledged access to the tools in ArcToolbox

Dan, I did non understood your answer ("the probably reason is...")

[DanPatterson]

the "shortcut" is adding a field from the table.  It doesn't allow you to specify or check Environments and other influencing factors.  Only Tools in ArcToolbox provide the access points to have full control of functionality.

A shortcut will by virtue, have defaults and anything outside of that realm "probably" disables the shortcut.

Hence, I always use tools in arctoolbox (or access tools via python) if the functionality exists there even if a "shortcut" exists.  

Historically the tools in arctoolbox have barely changed (except for enhanced functionality and perhaps movement with the toolsets etc).  Remember the "visual" transition from ArcMap to ArcGIS Pro... and the "where did X go?  where did button Y go?  Didn't happen for me since I largely use tools, if available, over shortcuts/buttons

Hi RobertoROssi,
I do not know if you may have solved your problem. Actually, your problem might be related to having an active edit session while you try to edit the other raster. I would recommend you save your project (Cntrl S), locate the Edit button on the ribbon, a Save button will be activated under the Edit. Hit it and try to Add Field again.
