ORA-30443: definition for filter string

's item string is invalid

What triggered the Error:

The specified filter is invalid. It contains at least one invalid filter item. If a filter item has a string list, it becomes illegal when the string list cannot be successfully parsed.

What should we do to fix it:

Remove the illegal filter with the purge_filter sub-program and redefine a correct filter
