expdp of partitioned table - export by range partition

Question

i'm tryng to execute expdp to export sme partitions of a partitioned table. I use

tables=oenwr.table query="where EVENT_TIMESTAMP < to_timestamp('2022-04-03 00:00:00','YYYY-MM-DD HH24:MI:SS')" (EVENT_TIMESTAMP is the column artition ) but export start from the last partition out of my range , anyway exports all partitions

.. exported "owner"."table":"SYS_P99999" 15.01 KB

Maybe it's not possible export selected partitions using a query by the partition column?

I could give a list: tables=owner.table:PART_01,..,..,owner.table:PART_09

but it's not very smart, i don't have the list, i have the EVENT_TIMESTAMP range (es. the last month for a DAYLY partitions.

Someone have an idea? It's seems like a product limit.

Thanks to all, Andrea
