An attempt was made to pass a current parameter to the formal parameter
"<runtime parameter>" of the form "<runtime parameter>", which does not have type C or STRING at

Parameter "<runtime parameter>" is typed with ANY so that both character fields as

generic type for types C and STRING yet, this check will only take
place at runtime.
