Teradata Partition Backup

Has anyone used the new feature partition backup. I am trying to take partition backup based on the example given on the manual and it is doing a full table backup skipping the condition.

I might be wrong on where clause...

If someone has done it before can share their knowledge.

I appreciate the help.

Script:
archive data tables
(edwwt.cpt_new_bk)
( partitions where
(! Transaction_Dt between current_date - 3 and current_date!) ),
release lock,
file=PPAmp1;
logoff;
