Answer / swetha
To perform the following tasks.
Get a related value. For example, if your source table
includes employee ID, but you want to include the employee
name in your target table to make your summary data easier
to read. Perform a calculation. Many normalized tables
include values used in a calculation, such as gross sales
per invoice or sales tax, but not the calculated value (such
as net sales). Update slowly changing dimension tables. You
can use a Lookup transformation to determine whether records
already exist in the target.
