Issue: When attempting to calculate a field on a simple junction layer with a table join, I get an error stating that I have to be in an edit session.
To recreate the issue:
- Create a trace network, including a point feature class as simple junctions.
- Add the junctions to a map.
- Add a field to the junctions. For this example, use type Double.
- Join another layer to the simple junction layer.
- Use the Calculate Field geoprocessing tool to calculate the new Double field. Or, just right-click the field name in the table window and click Field Calculator.
- Try to calculate any value. Even zero will suffice for this test.
In pro 2.6.3, I then get an error saying:
ERROR 999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds.
An edit operation is required. [WRProxyMZ]
Failed to execute (CalculateField).
In ArcMap, the workaround would be to click Editor > Start Editing. I don't know how to do that in Pro. Instead, my current workaround is to click a cell in the attribute table and write some bogus value, in this case zero, so that the edit tab on the ribbon has the Save button enabled. I believe this is the equivalent of having an edit session open. Then, I can calculate the field as normal. But, that seems kludgy, so what's the proper way of handling this issue?
Thanks!
