Hello. I am using the 'Join Field' GP tool for the first time. I am trying to add a field, and the data, from a FGDB feature class in Pro, where I added a new field and data, to the same feature class in our sde GDB, which does not have this new field. The sde feature class is in feature dataset that is registered as versioned. The editing option for the sde feature class is clicked on in Pro. I am using the 'Select transfer fields' parameter in the GP tool and choosing the field I want to add to my sde feature class. I do not have a field (null values) set up in my sde feature class to receive the data. I am assuming the field will be added. I have tried the GP tool using the our Default version and using my edit child version. Regardless, running the tool returns an 'ERROR 000499: table is not editable' message. What am I doing wrong? Many thanks in advance.
