A global variable was incorrectly created that contained 2 question marks, and now we cannot delete it.
Release : 12.0
If you need to manually delete some autosys global variable that contains non-ascii characters you can do so via a direct database update.
Example
Make sure you provide a partial name to get the single variable you want to delete...
select glo_name from aedbadmin.ujo_glob where glo_name like 'FDB_MAPS_MAPS_%';
Then you can delete it
delete from aedbadmin.ujo_glob where glo_name like 'FDB_MAPS_MAPS_%';
NOTE - Non-ASCII characters at the end of lines during your sendevent -E SET_GLOBAL commands can cause issues.
Make sure to remove any/all trailing non-ascii characters from your sendevents before issuing the commands.
