ELSE "NO".
C) Create a stage variable named sv_IsNewProduct and follow it by a second stage variable
named sv_Product. Map the Input.Product column to
sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product <> sv_Product THEN "YES"
ELSE "NO".
D) Create a stage variable named sv_Product and follow it by a second stage variable named
sv_IsNewProduct . Map the Input.Product column to
