Where Clause in the block not executed

Question

I have this in the where clause in my block, I want to exclude managers. I have added a flag column IS_MGR to prs_employee_profile and I added this line to query(where IS_MGR <> 2) “ value 2 for true” and but it doesn’t work. prs_amp_profile is the emp table and this block is based on atn_emp_week , emp_id is a foreign key. all the conditions are working except for the one i added and it is still bring the records for the managers. Any body can tell me why the condition is not being forced.
Original Where Clause
1=1 AND (emp_id in (select id from prs_employee_profile where
dpt_id in (select dept_id from prs_user_dept_priv where user_id = :global.usr)
and emp_id = decode(:global.emp_user_flag, 1, id, :global.emp_id)
and emp_sts_id in (select id from prs_employment_status where active_flag <> 0))
OR :GLOBAL.GRP='ATN_ADM')
After adding
1=1 AND (emp_id in (select id from prs_employee_profile where IS_MGR <>2
And dpt_id in (select dept_id from prs_user_dept_priv where user_id = :global.usr)
and emp_id = decode(:global.emp_user_flag, 1, id, :global.emp_id)
and emp_sts_id in (select id from prs_employment_status where active_flag <> 0))
OR :GLOBAL.GRP='ATN_ADM')

Answer 1

     1=1
AND (    emp_id in (select id
                      from prs_employee_profile
                     where IS_MGR!=2
                       And dpt_id in (select dept_id
                                        from prs_user_dept_priv
                                       where user_id = :global.usr
                       and emp_id = decode(:global.emp_user_flag, 1, id, :global.emp_id)
                       and emp_sts_id in (select id
                                            from prs_employment_status
                                           where active_flag!=0)
      OR :GLOBAL.GRP='ATN_ADM'
    )I don't know your table-structures, one possibility would be that :GLOBAL.GRP is ATN_ADM at testing for this overwrites the other conditions.
I would try to check the condition in sql*plus, apply it to the block when its working.
