Requested operation could not be completed error when symbolizing

RandallClark2

Hello old friends,

In ArcGIS pro 2.3 when i attempt to symbolize using "Unique Values" on a feature class that is joined to table i get the "Requested operation could not be completed".

I get this error regardless if i am symbolizing on one field or two or in a field in the feature class or the table, however when i remove the join guess what?

It works!

Can ArcGIS Pro 2.3 not handle symbolizing when in a join is in place or am i missing something?

Other notes:

Data is in a versioned enterprise sql database.

A coworker experienced this issue in ArcGIS Pro 2.9.5. Although we weren't able to get to the bottom of the problem (the "why"), we were able to get around it.

We changed the Unique Values field from what it was (Field A) to some other random field (Field
No error appeared, so we saved the project and exited ArcGIS Pro to start fresh
When we reopened the project, ArcGIS Pro crashed with an optional error report. We exited the report dialog
When we reopened the project a second time, ArcGIS Pro didn't crash
We changed the Unique Values field from what it was (Field to the original field (Field A)

And that solved it for us.

Solved: Are you working inside a OneDrive folder maybe? This was the reason for me at least. My default ArcGIS Pro>Projects folder was inside OneDrive by default, and this was apparently the reason for this bug. Hope it helps.

Alright - I think I found a solution for at least my case - that first heading that shows the longer field names? That came from the AGO version of the layer from which I imported symbology. The names are truncated in the .shp, obviously, and even though the symbology was referencing the truncated fields, the label of that heading was still showing up with the full names, and this was causing issues. I was unable to move or remove the "7, 0" class, but I could remove the heading and classes from the 3 dots. I then renamed the header with full names to the truncated names and re-added the value. It joined the first header and I am now able to modify the symbology, move it, remove it, etc.

I'm running into this today with Pro 3.0. It's just a plain old shapefile, symbolized by two fields. I'm able to edit the first three classes that I added some time ago, but unable to change the symbology of a value I added recently. I've tried closing/reopening, copying to a different map, etc.

I ran into the issue today, though I didnt have a join set up, the symbol was based on a field within the feature class. when I grouped some new values with an existing symbol (I wanted these new symbols to have a similar symbology which contains a few layers to build) to save from re building the symbol from scratch 4 times. But when I ungrouped them I couldn't change the symbology, and now I cant remove those symbol classes. when I try to I get the "requested operation could not be completed" error. so frustrating!

this is in a feature class in a file geodatabase, not SDE.

Still the same issue with ArcGIS Pro 2.8.1

The internal issue I referred to above is showing as fixed in ArcGIS Pro 2.5. That is scheduled to be released on February 6th so keep an eye out.

Hope this helps.

Has anyone found a work-around to this besides exporting to a filegdb or writing the join field to the original feature? Anything in Arcade? Thanks

AnnaLM

Is there any update to this bug?

KoryKramer

Sorry that you're running into this. I shared this with the development team and they are able to reproduce the error when working with a versioned table with a join and unique values. They have logged this as an issue to get fixed.

I Have the same question like yours, Have you solved the problem yet? How to solve it ？

My version is ArcGIS Pro 2.3.2

I had same error message "Requested operation could not be completed" when attempted to change symbology from Single Symbol to "Unique Values" (this feature class has more than 100 unique values). I also noticed followings.

1. Failed to open its attribute table (getting message something like "Could not load the data, General error...."

2. I was able to view same feature class in ArcCatalog 10.5.1

3. I was able to view same feature class in ArcGIS Desktop 10.5.1. and able to change symbology to Unique Values

After attempting to fix this issue with my limited knowledge (refresh, remove feature class from Contents Pane and add it again, close the project and reopen...), my application suddenly closed without any warnings. I then open it and the issue was fixed!!

I have no idea as to why or how this happened but thought to share what I experienced.

I'm not able to throw the error in same environment and workflow. Exact steps to reproduce? What type of SQL database? What version of SQL? What type of versioning? Where is the table? What kind of Join? How many records in the feature class? How many records in the table? Same error if you bring the data into a FGDB? This is probably best solved with a call to tech support.

Did you ever figure this out? I too am having this issue.
