Subject Creating foreign keys
Author marcel_nic
Hi all,

I'm trying to create a foreign key between 2 tables while 2 or more
connections to the database are active and I get an error like this

This operation is not defined for system tables.
unsuccessful metadata update.
object REFERENCED_TABLE is in use

Is this a normal behaviour (while any other changes are alowed - i.e.
add or delete fields, delete FK-s)

Thanks, Marcel
