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.

if i have records like these (source table) rowid name 10001 gdgfj 10002 dkdfh 10003 fjfgdhgjk 10001 gfhgdgh 10002 hjkdghkfh the target table should be like these by using expression tranformation. (Target table) rowid name 10001 gdgfj 10002 dkdfh 10003 fjfgdhgjk xx001 gfhgdgh xx002 hjkdghkfh (that means duplicated records should contain XX in there rowid)
