About Partitioned Primary Index (PPI) - forum topic by Kbos

Hi everyone..
Well, I have a table with the following structure and I need to add  a new RANGE by adding the field People_Subscription_Start_DT:
PARTITION BY RANGE_N (People_Subscription_Start_DT DATE '2008-09-01' AND DATE '2013-12-31' EACH INTERVAL '1' DAY, NO RANGE);
 
My question to all of you is: Do I need to add the field People_Subscription_Start_DT as part of the PPI? Is it a MUST when adding a RANGE to put the field as the PPI?
 
Thanks in advance
