Something is not right here. Stephen. Here is your query:

SLDC>    select /*+ NO_MERGE(Z) NO_PUSH_PRED(Z) PUSH_SUBQ(Z) */ distinct
SLDC> nbr_cc_fop_name into v_fop from
SLDC>       (select nbr_cc_fop_name, nbr_cc_fop_high, nbr_cc_fop_low
SLDC>         from nbr_cc where nbr_cc_fop_name in ('AX','MC','VI','DS')) Z
SLDC>       where to_number(trim(substr(p_corigid,1,20))) between
SLDC> to_number(trim(nbr_cc_no_low))
SLDC>       and to_number(trim(nbr_cc_no_high));

How can this even work? Your outer WHERE clause references columns that do not exist in the table returned by your subequery.

I built an nbr_cc table and ran your query. Below are the results I get:

SQL> select distinct nbr_cc_fop_name into v_fop   2 from ( select nbr_cc_fop_name, nbr_cc_fop_high, nbr_cc_fop_low

  3         from nbr_cc
  4         where nbr_cc_fop_name in ('AX','MC','VI','DS')) Z
  5  where to_number(trim(substr(p_corigid,1,20))) between
  6           to_number(trim(nbr_cc_no_low))
  7           and to_number(trim(nbr_cc_no_high));
         and to_number(trim(nbr_cc_no_high))
                            *

ERROR at line 7:
ORA-00904: "NBR_CC_NO_HIGH": invalid identifier

While NBR_CC_NO_HIGH *does* exist in nbr_cc, it does not exist in the table Z that is returned from the subquery.

What am I missing here? So far as I can tell, the above query should not even execute for you.

SQL> describe nbr_cc
