Hi,
If I understand your question correctly, then it is like-
How to send original (distinct) records to one target
(let's say TA) and duplicates to another target (let's say
TB).
It can simply be done as follows -
In your mapping, take the source table containing whole
records (duplicates as well). Now, take 2 source qualifier
(SQ) transformations. The first SQ should
contain 'Distinct' sql query (hope you know that) and the
output ports should go to TA table.
The second SQ should contain the following sql stmt (which
filters only the duplicate records) -
-------------------------------------------
SELECT empno, ename, job, mgr, hiredate, sal, comm, deptno
FROM (SELECT empno, ename, job, mgr, hiredate, sal, comm,
deptno, ROW_NUMBER() OVER (PARTITION BY empno ORDER BY
EMPNO) rn FROM s_assign_1_emp)
WHERE rn > 1
-------------------------------------------
I am using emp table example (hope you can understand it).
Now, the output ports of the seecond SQ should go to TB
table.
This is the simplest way of doing it. Hope it will help.

Hi, I saw one mapping implemented by my seniors . In Expression transformation they implemented following logic. That is iif(is_date(in_UC_DATINV,'YYYYMMDD'),to_date(in_UC_DATINV,'Y YYYMMDD'),'Inventory Date is either invalid or null') Inventory_Date is validated only for is_date() But not validated for notisnull() . But error says “ either invalid or null “ why? Whether is_date() also check for not isnull() ? or in this logic something is different ? Please answer me . Advance thanks
