create table update_emp
(
empid varchar2(10),
emp_value_code varchar2(5),
emp_sub_code varchar2(5),
update_flag char(1)
)
create table mstr_uemp

)
insert into mstr_uemp (emp_value_code,emp_sub_code) values ('IN','IN001');
/
insert into mstr_uemp (emp_value_code,emp_sub_code) values ('CS','CS001');

Begin
select count(*) into cnt_flag
from table mstr_uemp
where emp_value_code = p_type_code and

You have created a function whose name is "fn_get_cr133_uflag", but in a control file you use "fn_get_subtype_flag". Also, as there's no fourth column value in the input file, you need to specify TRAILING NULLCOLS. Once you modify it, the result is as follows (tables and function are precreated):
Control file
LOAD DATA
INFILE *
append INTO TABLE update_emp
FIELDS TERMINATED BY '§'
trailing nullcols
(
empid integer external,
emp_value_code char(5),
emp_sub_code char(5),
update_flag "fn_get_subtype_flag(:emp_value_code,:emp_sub_code)"
)
begindata
1§IN§IN001§
2§CS§CS001§
3§SI§SI001§
