??? Are you talking about the TD systems in your company?
Some remarks:
A NOPI table doesn't have a PI, that's why it's called NOPI.
SET means a logical Primary Key across all columns, a new row must be checked if it's duplicate. On a SET table this will be done for all rows with the same PI/RowHash. WIthout PI it would mean checking against every row in the table.
