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

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.

Hello everyone, thanks for bringing this issue to our attention. BUG-000144887 was logged for this issue, and the current status of the bug is 'In Product Plan'.

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

danretired

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

Thanks DanPatterson,

The same for me

The same for me.

So, recapping:

If you try to add a field straight from the Table view: it doesn't work
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
you can always Add field via the Add Field Geoprocessing tool (also without building the Raster Attribute Table with the geoprocessing tool)

Thanks curtvprice, no edit session open, no messages when I use the Add Field Tool.

Do you think the problem (for the Add field command unavailable in the table view) could be the file naming?

danretired

but there is a workaround...

so off to Tech Support I suppose.

reference this thread

curtvprice

Maybe a 2.9 bug?

danretired

integer raster, it works from the toolbox, not the table. Pro 2.9

Path and filename are short and checked.

BUT

Build raster attribute table

Go to Fields View

Add field

curtvprice

Yes, Add Field button worked fine for me with a raster .tif table. I would make sure you don't have an edit session open. It's possible file naming is an issue, and there are so many things that can make a layer non editable and it is sometimes not easy to diagnose! Try the Add Field tool maybe you'll get a useful error message.

RobertoRossi

Thanks curtvprice, but my files are tif rasters, and the Add field button doesn't work.

Are your able to use it with your files?

RobertoRossi

nothing changes with Build Raster Attribute table, neither with, nor without the Overwrite parameter

curtvprice

I checked this, in Pro 2.8. It looks like you have an Esri Grid (the OID tipped me off); the raster table is an INFO table. It appears the Add Field button does not work with Esri Grid tables. Funny, because you can edit the INFO table contents!

If you convert the raster to .tif (I recommend this) or FGDBR you can add a field from the attribute view. However (interestingly) the Add Field tool works fine to add fields to an Esri Grid INFO table.

see if this updates the situation
