1.Sort the data
2.Expression transformation
a)create a variable1(integer) and var2(string)
b) var2 = concatenate all fields
b) set the value of the variable to 1 if (concat all fields are = var2)
c) create a o/p port = var2
-- output of the expression t/f will be like
NAME ID NEW_COL
a 1 0
a 1 1
b 1 0
b 1 1
c 1 0
3. Use a router transformation and route the data based on the new thirt column.
