Attempts to execute the "Add Field" tool fail with "Error 000496 table is being edited" which is NOT true. I am attempting to automate adding many default organization fields to many FC's sitting in ArcSDE workgroup on SQL express, 10.0, desktop is 10.0 (patched). FC is in a FD, registered as versioned, with default, qa, and edit versions. All edits have been previously rec'ed and posted, DB compressed, and NO ONE is attached to the DB editing (why I'm in here on sunday doing this!). I have rebooted the SQL server, the workstation, un-registered and re-registered the FD as versioned, performed all the DB maintenance tasks, change the field name and type, tried other FCs, under no circumnstance or permutation of options can I get the add field tool to work. It always returns "Error 000496 table is being edited". How do I find and kill this mysterious schema look that is preventing me from adding fields to FC's?
