Sql to verify the calculation of end_date of SCD2 dimension

Question

create table SRC
(CUST_no    NUMBER(9,0),
C_TYPE      VARCHAR2(2),   
EFFECTIVE_DATE    DATE(7));
INSERT INTO SRC VALUES('56039', 'MM', '1/04/2010');
INSERT INTO SRC VALUES('56039', 'RS', '10/08/2011');
INSERT INTO SRC VALUES('16039', 'MM', '1/04/2011');
INSERT INTO SRC VALUES('17039', 'XM', '1/04/2011 10:00:00');
INSERT INTO SRC VALUES('17039', 'MM', '1/04/2011 13:00:00');
INSERT INTO SRC VALUES('17039', 'OS', '5/04/2011');
commit;
create table TARGET_RESULT 
(t_KEY    NUMBER(22),
T_CUST_NO    NUMBER(9,0),
T_C_TYPE      VARCHAR2(2),
EFFECTIVE_DATETIME    DATE(7),
END_DATETIME    DATE(7),
DW_CURRENT_FLAG    VARCHAR2(1));
INSERT INTO TARGET_RESULT VALUES('a123','56039', 'MM', '1/04/2010', '09/08/2011 23:59:59', 'N');
INSERT INTO TARGET_RESULT VALUES('a125','56039', 'RS', '10/08/2011', '31/12/2999', 'Y');
INSERT INTO TARGET_RESULT VALUES('b222', '16039', 'MM', '1/04/2011', '31/12/2999', 'Y');
INSERT INTO TARGET_RESULT VALUES(‘c111’,'17039', 'XM', '1/04/2011 10:00:00', '01/04/2011 12:59:59', ‘N’);
INSERT INTO TARGET_RESULT VALUES(‘c124’,'17039', 'MM', '1/04/2011 13:00:00', '05/04/2011 23:59:59', ‘N’);
INSERT INTO TARGET_RESULT VALUES(‘e111’,'17039', 'OS', '5/04/2011', ‘31/12/2999', ‘Y’ );
commit;Rules for Target_Result table;
i.     Check if the incoming (src) and target current record are different (at least for one chosen attribute)
ii.     If they are same, do nothing
iii.     If they are different, do the following
1)     For the record in the target table, change (update) the END_DATETIME to (EFFECTIVE_DATETIME - 1second (i.e effective_datetime-1/(24*60*60)) of the succeeding record and set the DW_Current_flag to ‘N’
2)     Take the incoming record (src), generate a surrogate key, enter source record’s date as the EFFECTIVE_DATETIME and the default date as the END_DATETIME (31/12/2999). Also set the DW_Current_flag to ‘Y’. Insert into the dimension
I want to take the source table and apply the SCD2 rules to verify/test rule (1) has been executed correctly in the target_result table (i.e SCD Type 2 dimension) .
How can it get the correct succeeding record and verify the rule.
Am using Oracle 11g.

Hello,
do you know where can I configure "Total Compensation Statement"? I'm working in ERP 2004.
I've created a new form in Smart Forms and now I want to change the default form used in the Portal.
Thanks a lot
Antonio
