We are running 9.3.1 SP1 with Oracle. Upgrading to 10 later this year.
During our initial efforts to edit the feature class through toolbox, it was versioned and the error we would receive when running the delete features tool was "Unable to edit versioned table". At that point we had the feature class unversioned which then gave us the "Insufficient Permissions" error.
We were able to test running the tool as the schema owner and it was successful. Unfortunately due to organizational restraints, we won't be able to login as the schema owner to run the tool. Is there any other way around this?
Currently the process being used is to load the feature class into ArcMap, start editing, select all and delete. Then load the new data into the feature class in Catalog.
