Oracle Solution for Error ora-30688

ORA-30688: maximum program calling depth exceeded

What triggered the Error:

Your program contains a set of calls that are too deep to be handled. Only transitions between the different execution engines (SQL, PL/SQL, and Java) count in reaching this limit; calls within the same engine don't count.

What should we do to fix it:

Restructure your program so as to not call so deeply. Perhaps some recursion can be replaced with iteration.
