FUNCTION fn_check_date(pd_sn_earliest_start_dt IN i2_sn_details.earliest_start_date%TYPE,

pn_sn_min_duration IN i2_sn_details.minimum_duration_weeks%TYPE,
pd_tn_earliest_start_dt IN i2_tn_details.earliest_start_date%TYPE,
pd_tn_latest_end_dt IN i2_tn_details.latest_end_date%TYPE,

pn_date_margin IN NUMBER)
RETURN BOOLEAN;
FUNCTION fn_check_degree(ps_sn_degree IN i2_sn_details.degree%TYPE,

You need to get that revised code into the database - what you are doing with the 'alter package' command is simply recompiling what is already in the database (not your new code).
In SQL*Plus:
sql>@c:\myfile.sqlwhere c:\myfile.sql is the name of the file.
Running this script will then replace the code stored in the database with the new code from your file.
