PPI - response (2) by macktd

Hi, Pawan Thanks for your response,
Actually i defined UNIQUE PRIMARY INDEX (Customer_Number, Order_Date)
As per our rule, UPI can't be allow in PPI, Eventhough i defined UPI has Order_Date as well as  I have used in partition. Table was created successfully.
While i'm inserting on table below
ins into order_table (101,'mack', current_Date,1000);
row inserted.
ins into order_table(102,'pawan',current_date,2000);
row inserted.
But order_date(UPI) allows the duplication why?
 
Thanks&Regards,
Mack.
