Sorry, maybe I didn't explain my problem properly.
Using a third party software, I just Extract a DDL for source table (It's atacched to this comment, TRTEEVENTS_ORG_DDL.txt)
Then the only partition on wich I am interested is Partition P_2005_01 on the source table, so I created a new bkp_table using the DDL from source table only for this partition.
