I just opened a pro project that was created pre 2.5 upgrade. I can see my data as expected.
When I try to re add that table to that project or any other made after the upgrade we get an error.
FAQ: What characters should not be used in ArcGIS for field names and table names?
After looking into it, I believe that the error is because pro is adding quotes to field names. Only on the layers that have a _ before hand. This did not happen in a pre Pro 2.5 project and does not happen in desktop products. I downgraded to 2.4 and the table added without the quotes.
We do not have access to the database and cannot change the field names.
Any suggestions on a work around?
Thank you for suggestions. At this point we have not been able to fix this issue. I will post back here with updates in the future.
