Hi David,

Normally, you would not restrict deletion of a child record if a parent record exists, but I guess anything can be written into a custom RI routine.

Another thing to check: Since you are using optimistic buffering, could there be another process with the table open (maybe a cursor/view that uses the table) that might prevent the lock from occuring to perform the delete?
