Answer / vijay
Are you saying you want the first 7 records from the source
table?
If that is the case, write an override in source qualifier
and fetch by the row number. That would be the fastest
way.Load into target.

Answer / amedela chandra sekhar
IF U WANT LOAD 7 RECORDS FROM SOURCE TO TARGET,
WE CAN USE SEQUENCE GENERATOR T/R
CURRENT VALUE =0
END VALUE =7
RESET ENABLE
THEN DRAG THE NEXTVAL PORT TO EXP T/R
CREATE ONE OUTPUT PORT GIVE THE CONDTION LIKE NEXTVAL =7.

Answer / sameer
If ur source as a flat filemail then we uses first expression transformation and we write expression v1=v1+1 and one output port o1=v1 then after filter transformation and in there filter conditions just write o1 <=7 But if ur source as a relational source then we write select * from table-name
Where rownum <=7
