Hi every one 

I have created a procedure ASY.EUTR_CVS with these arguments:

create or replace procedure ASY.EUTR_CSV(
arg_startdate gen.sad_asmt_date%TYPE,
arg_enddate gen.sad_asmt_date%TYPE,
arg_filename gen.sadmanif_nber%TYPE
)
AS

cursor c_data

IS 
     SELECT

v_file    UTL_FILE.file_type;
BEGIN
 v_file :=
     UTL_FILE.fopen (LOCATION     => 'EXTRACT_DIR',
                     fielname     => arg_filename,
                     open_mode    => 'w',
                     max_linesize => 32767);
FOR cur_rec IN c_data
LOOP
UTL_FILE.put_line (v_file,      );
END LOOP
 UTL_FILE.fclose (v_file);
EXCEPTION
    When others
     THEN
      UTL_FILE.fclose (V_file);
END;


the procedure is created but when i do a  exec ASY.EUTR_CVS
i get:
Error at line 1
ORA-06550 line 1, column 7:
PLS-000306: wrong number or types of arguments in call to EUTR_CSV
ORA-06550 line 1, column 7:
