Help with a function

Question

I have the following records in a table
SARAPPD_PIDM     SARAPPD_TERM_CODE_ENTRY     SARAPPD_SEQ_NO     SARAPPD_APDC_CODE                   SARAPPD_APDC_DATE
2232040            200990                                                   1                       S*                                    12/03/2008 16:30:45
2232040           200990                                                  2                       D1                                    12/08/2008 07:40:52
2232040           200990                                                 3                       S*                                      03/18/2009 08:58:06
2232040           200990                                                   4                       WL                                   03/21/2009 13:53:23I need to write a function to show only if the SARAPPD_APDC_CODE code is
AND TRUNC (sarappd_apdc_date) >=
saturn_midd.utlq.f_get_adm_freeze_date
(saradap_admt_code));
This is another function...
If the sarappd_apdc_date) is <= than saturn_midd.utlq.f_get_adm_freeze_date
(saradap_admt_code));
I need to show the previous SARAPPD_APDC_CODE
In another words:
WL is the latest decision, but I can display it only if APDC date is > than      saturn_midd.utlq.f_get_adm_freeze_date
(saradap_admt_code));
THE RESULT OF THIS FUNCTION
saturn_midd.utlq.f_get_adm_freeze_date
(saradap_admt_code));
is 3/28/2009

AS you can see the WL is the last decision but that decision was made on 3/29/2009 and the freeze date is 3/29/2009, the decision date is grater than 3/28/2009
the freze date, so I need to show the previous one S* with the decision date of 03/18/2009 08:58:06Actually, I can't see. I can't see 3/28/2009 anywherre in the data.
Without the sample data from all the tables, I can only guess. I'm willing to make one guess:
You may need to use the analytic ROW_NUMBER fucntion to assign numbers to the possible rows
ROW_NUMBER () OVER
    (ORDER BY CASE
                     WHEN  sarappd_adctivity_date < freeze_date
                     THEN  sarappd_activity_date
              END
     DESC
    ) AS rnumand then pick only the row WHERE rnum = 1.
If you want to post formatted text, like query results on this site, type these 6 characters:
(small letters only, inside curly brackets) before and after formatted text, to preserve spacing.
