FUNL0049 Record (recno) unexpectedly missing.
A record that was found in the existence bit map (or found set) was missing from the database file. This could be the result of running with the NOENQ parameter against a database file that is being updated, or of running against an unenqueued found set or list when using the Fast/Unload User Language Interface. You can change the action to be taken when this situation is encountered by setting the HARDERR parameter. The default action is to cancel the run.
