Answer / gyana

yes..very nice question

---------------------------
after SQ take two pipeline::::one to find 1st 3 record and another to find last 3 record
------------------------------------------
(1) from SQ connect an expression and into that expression connect a sequence generator to generate sequence.
After expression put a filter t/r (seq>=4) and pass to one target instance(T1)
(2) from SQ connect an expression and into that expression connect a sequence generator to generate sequence.
now take a RANK t/r and set the property as(bottom performer,rank on port SEQ,NUMBER OF rank=3).connect that to second target instance (T2)..it will give u last 3 records..

if any wrong pls send me mail......(gyana.informatica@gmail.com)

For stage table data processing, suppose in first run we processed 8 records out of 10 records then in 2nd run we should consider only not processed records (here total no of records =2) along with new records which got loaded in stage table thru real time mapping. Note : In this example, 8 records are those records for which we got transaction number after lookup on trn_no_cod table and 2 records for which lookup returns trn_no as NULL
