ORA-06573: Function [string] modifies package state, cannot be used here
Cause: There are two possible causes for this message:* A SQL statement references a packaged, PL/SQL function that does not contain a pragma containing the ''Write no Package State'' (WNPS).* A SQL statement references a stand-alone, PL/SQL function that modifies a package state. A stand-alone, PL/SQL function referenced by a SQL statement cannot modify a package state.
Action: If the function is a packaged, PL/SQL function: Recreate the function and include a pragma containing the ''Write no Package State'' (WNPS). If the function is a stand-alone, PL/SQL function: Delete the function from the SQL statement.
Error Type: ORA
