Call function in the package ....

Question

I have interesting problem. It's interesting because it works on one server and does not work on another, both servers are ORACLE 10.2.0.2 on Solaris 10, both have identical users.
when I call pkg_utilities_public.GET_CURRENT_POST_DATE (sysdate) I get correct result on one server and error ORA-00904: "PKG_UTILITIES_PUBLIC"."GET_DATE": invalid identifier on the other, I have a user with DBA rights ...
what's even more interesting that I can compile this on both servers with no issue
the issues is how I call GET_DATE, I call it as GET_DATE instead of PKG_UTILITIES_PUBLIC.GET_DATE (lazy way but still should work on both) any idea why this works on one server and not the other? If I call it with PKG_UTILITIES_PUBLIC.GET_DATE it works on both, so I have solution, but I'm wondering why the first thing does not work.
CREATE OR REPLACE PACKAGE FDM.PKG_UTILITIES_PUBLIC AUTHID CURRENT_USER IS
--- GETS DATE BASED ON PERIOD_KEY (return YYYYMMDD or YYYYMM)
FUNCTION GET_DATE (v_period_key number:= 0) RETURN NUMBER ;
--- if today is post_dt get today, if not get previous post date
FUNCTION GET_CURRENT_POST_DATE(v_date DATE) RETURN DATE;
END;
CREATE OR REPLACE PACKAGE BODY FDM.PKG_UTILITIES_PUBLIC IS
--- GETS DATE BASED ON PERIOD_KEY (return YYYYMMDD or YYYYMM)
FUNCTION GET_DATE (v_period_key number:= 0) RETURN NUMBER is
v_date number;
BEGIN
SELECT DECODE(PERIOD_TYPE_CD,'D',TO_CHAR(PERIOD_DT,'YYYYMMDD'),'M',MONTH_OF_YEAR_CD, 0)
INTO v_date
FROM FDM.PERIOD
WHERE PERIOD_KEY = v_period_key;
RETURN v_date;
end GET_DATE;
--- if today is post_dt get today, if not get previous post date
FUNCTION GET_CURRENT_POST_DATE(v_date DATE) RETURN DATE IS
v_output_dt DATE;
BEGIN
SELECT TO_DATE(GET_DATE(DECODE( POST_DT_FLG,'Y',PERIOD_KEY,'N', PRIOR_POST_DT_KEY)),'YYYYMMDD')
INTO v_output_dt
FROM FDM.PERIOD
WHERE PERIOD_TYPE_CD = 'D'
AND PERIOD_DT = TRIM(v_date);
RETURN v_output_dt;
END;

speaking technical and not personal, I think this is related to serilization of SQL engine from PLSQL engine,
both samples below work on SERVER A,
sanple 1 does not work on server B, sample 2 works on server B (you can see I removed the call from SQL into PLSQL (this is generally better approach).
FUNCTION GET_CURRENT_POST_DATE(v_date DATE) RETURN DATE IS
v_output_dt DATE;
BEGIN
SELECT TO_DATE(GET_DATE(DECODE( POST_DT_FLG,'Y',PERIOD_KEY,'N', PRIOR_POST_DT_KEY)),'YYYYMMDD')
INTO v_output_dt
FROM FDM.PERIOD
WHERE PERIOD_TYPE_CD = 'D'
AND PERIOD_DT = TRIM(v_date);
RETURN v_output_dt;
END;
FUNCTION GET_CURRENT_POST_DATE(v_date DATE) RETURN DATE IS
v_output_dt DATE;
v_my_date NUMBER;
BEGIN
SELECT DECODE( POST_DT_FLG,'Y',PERIOD_KEY,'N', PRIOR_POST_DT_KEY)
INTO v_my_date
FROM FDM.PERIOD
WHERE PERIOD_TYPE_CD = 'D'
AND PERIOD_DT = TRIM(v_date);
v_output_dt := TO_DATE(GET_DATE(v_my_date ),'YYYYMMDD');
RETURN v_output_dt;
END;
