First in the pre_session command task remove the duplicates
using the following
cut -d "," -f2 filename|uniq
Now in the file you will have
3000
4000
5000
2700
4500
now after source qualifier keep a expression and generate
the sequence.
Hope it clarifies

Answer / jayachandra
One solution is use distinct key word on source qualfier as
suppose your table name is emp than on emp_sq
the query is
select emp_no,distinct sal from emp;
2nd sol is make an aggregator transformation here make a
coun()on sal port with group by then put filter
transformation with condition count(sal)=1

Suppose we have a (assume relational) source table Product_Id Month Sales 1 Jan x 1 Feb x . . . . . . 1 Dec x 2 Jan x 2 Feb x . . . . . . 2 Dec x 3 Jan x 3 Feb x . . . . . . 3 Dec x . . . . . . and so on. Assume that there could be any number of product keys and for each product key the sales figures (denoted by 'x' are stored for each of the 12 months from Jan to Dec). So we want the result in the target table in the following form. Product_id Jan Feb March.. Dec 1 x x x x 2 x x x x 3 x x x x . . So how will you design the ETL mapping for this case , explain in temrs of transformations.
