7/21/2019 Rank Index
1/1
What is the Rank index in Rank transformation?
Ans: The Designer automatically creates a RANKINDEX port for each Rank transformation. The Informatica Server uses the Rank Index port to store the ranking position for each record in a group. For example, if you create a Rank transformation that ranks the top 5 salespersons for each quarter, the rank index numbers thesalespeople from 1 to 5.
