ArcGIS Pro: Polyline Symbology error: "Requested operation could not be completed"

ElieRizk — Fri, 12 Jul 2024 07:04:31 GMT

The issue persists in AGP 3..3.1 it is a show stopper to work with complex symbology for polyline layers. we are not able to move forward with such behavior. it is noted, the issue faced when using a feature class stored in file geodatabase and enterprise geodatabase.

we tried the steps mentioned in the following ESRI technical support page without success.https://support.esri.com/en-us/knowledge-base/error-requested-operation-could-not-be-completed-00002...

Also, someone mentioned that ESRI categorized this issue as a bug, but we aren't able to find the bug number.

"@ABishop kindly can you head up to the number of the bug mentioned in the URL you inserted in your message?

Here is a link to the BUG report site: https://support.esri.com/en/Search-Results#search?q=arcgis-pro&content-type=Bugs"

thank you,

ER,

I had this a few weeks ago.
Could not figure it out and have not had time to lodge a bug; but did lodge a few Ideas.

All I can say is unless you specifically use 3.3 functionality just revert to 3.2/earlier.

I am having this same issue. Apparently it has cropped up in several ArcPro versions. Sure be nice to get this fixed.

sorry for being late in replying.

I solved this issue by using unique value symbology with auto-generation (list all values) and then changing the symbol for each value separately. that's worked for me.

I can confirm this same behaviout with lines but It's also happening with polygons. I don't seem to be able to modify or add composite symbols in an existing pre v3.3.1 layer. (anything composed of more than the 2 default symbol layers). The only solution seems to be to add the layer into the map and build new symbology from scratch. When I get the "Requested operation could not be completed" warning, i am not able to same the symbol or layer symbology.

I'm having the same problem with point symbology. I can't apply any complicated/multi-layer symbols from the gallery. Adding a second layer to a basic point symbol and then trying to choose a more complicated symbol from the galley sometimes works. Both the error and that workaround are not consistent.

I have this same problem for a line feature. I have multiple complex line symbols I'm using for a set of trails in a local park, and I need to change some of them symbology wise. Now, I can't change anything and will be time consuming to re create this in a new layer from scratch.

I had the same problem. My work around - The symbol happened to be in a .lyr file originally created in ArcMap. I removed the layer from ArcGIS Pro. I was able to work on the .lyr file in ArcMap to update the symbology and then add it back into my ArcGIS Pro map. It worked, but it took me about two hours to figure it out. If the symbol is not in an old ArcMap file, then you are probably out of luck.

I am experiencing very similar problems. It seems to happen more often on feature classes I have created from DGN files and then stored in a file GDB.

I think this issue doesn't matter if it's point, line or polygon... I also had this error popup in a map after upgrading from v2.9 to v3.3 - I wasn't able to use my saved "complex" point symbology - my colleague suggested adding the layer into the map fresh... that seemed to work - unfortunately I now need to re-symbolize my layer... but at least I can used my saved symbol templates. Win?? *sigh*

This worked for me but it would be very nice if it didn't need to happen. Please fix this bug in 3.3 Esri! I work for a large Enterprise company that isn't on 3.4 yet.

Update: my workaround was to create the symbology in 3.5 and import it via a layer in 3.3.5.

I am experiencing this problem in Pro 3.3.5. I have a point layer using Graduated Colors Symbology. Each class has two symbol layers. When setting the properties of the second class the 'Requested operation could not be completed' shows up.

1 of 4 classes set, working on the 2nd class:

Attempt to create a new symbol layer on second class:

I'm joining the club! Getting this error in 3.6.2 after upgrading from 3.5.x. Working with polygons, stored in file gdb, no joins, multi-layer symbols (but having a fill and an outline are already two symbol layers). Does not seem to affect all maps in the project, but (of course) the most complex ones, which would be a pain to have to rebuild (they are also used in layouts that took ages to build).

ESRI is really sh*ttin the bed on this one.. one of the most imporant factors in creating maps is symbology... not these new tools (eg AI)... get it togehter ESRI and fix this critical issue..

Hi, I tried this and it allowed me to change the color of my lines if they are single layer symbol but not if they are more than one layer. The moment I try to add another layer to the symbol I get the same error. Did this happen for you as well?
