Hello Saurabh,
Include all the primary key fields in the where clause for PA0015 and PA0589, while comparing with those in PA0000. Since the key fields for all these '3' tables are same this should not be a problem.
If you have any reservations about changing the select query, then, sort your final internal table with a defined sort key (based on your requirement) and use "Delete adjacent duplicates" with the same sort key.
Please let me know if this helps.
