Which is the part that you don't undestand in "invalid DDL operation in system triggers"?

Read the (F) documentation:

"Cause: An attempt was made to perform an invalid DDL operation in a system
trigger. Most DDL operations currently are not supported in system triggers.
The only currently supported DDL operations are table operations and ALTER?COMPILE operations."
