Function: I get ORA-04063 if I try to execute from another schema

Question

Hi All,
I have a schema named "SCHEMA_A" and in this schema I have a function named TEST" that gets a numeric parameter "ID" and returns a string.
Then I have a schema named "SCHEMA_B" with a grant on functions SCHEMA_A.TEST. I want to use function "TEST" from SCHEMA_B.
If I try to execute SELECT SCHEMA_A.TEST(1) FROM DUAL inside schema SCHEMA_B I get ORA-04063.
But if I try to execute TEST(1) from owner schema (SCHEMA_A) and then again from SCHEMA_B it works. But it works only for parameter with value = 1.
If I try SELECT SCHEMA_A.TEST(2) FROM DUAL I get again ORA-04063. It seems that to use a specific value for function parameter, I need to execute first in the owner schema and only after that I can execute from the other schema.
Function code is very simple:
+CREATE OR REPLACE FUNCTION TEST(ID IN NUMBER)+
+RETURN VARCHAR2+
+IS+
+l_return VARCHAR2(256);+
+BEGIN+
+l_return := 'hello world';+
+RETURN (l_return);+
+END TEST;+
I use Oracle 11g R2.
Any idea why it happens?...

I can compile and grant as you did.
But if I try to execute from a schema different by owner (in your case SCOTT) something like
SELECT <your schema>.TEST(1) FROM DUAL
I get an error.
To fix, I have to execute this function in the owner schema with exactly the same parameter.
If I execute with a parameter in the owner schema (suc as 1,2 and 3), I can execute also in schema different by owner (in your case SCOTT). But if I try with a new parameter (es: 4) from SCOTT it give me an error.
Strange...
