ArcGIS Pro Requested operation could not be completed

[JasonHarshman]

I am using ArcGIS Pro 1.1 and trying to make some symbology changes on a feature class. Specifically, I am trying to format all symbols and trying to sort the label. In each instance, I get the error banner on top of the Symbology pane saying "Requested operation could not be completed." I'm new to Pro so I have no idea what this means or where to even begin troubleshooting other than closing Pro and trying again - which doesn't work.

Thanks,

Jason

Here's the error:

I'll have to try that out. I did a clean uninstall/reinstall the other day and still face the error. The most frequent encounters I have with it is when grouping/ungrouping/rearranging symbol classes or when modifying the drawing order of a group after grouping symbol classes within one of the group's layers. I have a tech support case open and they have indicated that they've been seeing similar issues lately.

I'm having similar issues in 3.0.2. Not only can I not group layers, I can't remove the layer that I added.

I am running 3.0.3 and am working on a project that has been months in the making.

i have not experienced this before. my workflow hasnt changed. the polygon feature class (in a .gdb) is not a new type, just recently regenerated after editing arcs. i applied the symbology from another layer... then this problem. i am trying to add a unique value (new code from the same attribute used to symbolise to date), and get this message. i cant sort the symbology pane, cant adjust the symbology of the new attribute. cant do anything really. i have restarted, remade the polygon in another database, emptied my cache....etc basically tried all the tips here.

how can this errror/bug/whatever still be the same over the course of software updates from 1.0 to now....3.0.3!!?? come on ESRI!

I'm running 3.1.0 and having this issue on a feature class in an SDE database. I've encountered the issue previously and had hoped it would be fixed by now... I've tried re-adding the layer, closing and restarting the software, clearing cache, and no luck.  I need to group symbology classes, and keep getting that same "The requested operation cannot be completed" error. Very, very frustrating... this is a basic software function without which I cannot perform my job.

i feel the pain. this 'support' process feels very much like yelling into the void.

pointless. unfortunately.

I recently ran into this issue today in 2024 so I was bummed to see that this 9 year old issue still exists and the solution is to reach out to support. That isn't a solution!

Ran across this recently also.  I am not sure what symbology method you are using, but I was trying to symbolize on Unique Fields, Adult Trauma and Pediatric Trauma, and was not able to update the symbology (except for a few very limited and old sumbols).  I ended up creating a Field call Trauma, field calculated it to 'Adult: ' + !ADULT_TRAUMA! + ' ; ' + 'Pediatric: ' + !PEDIATRIC_TRAUMA! 

This allowed me to basically use a single field for unique values, and I am able to create the symbology using the symbols I wanted to.  (BTW, I have a Hospital layer that I want to display whether and what level trauma center is available for Adult and Pediatric Patients, Not sure why the two field method won't allow the symbols to be chosen.

Still working on cleaning up the descriptions, but at least that is one hurdle overcome.  I agree, this should not still be a recurring issue, and It looks like maybe it is hit or miss, I just updated to 3.3.2, not sure if the version has anything to do with it.

Scratch that, it is screwing up again!!!!
