Checking HANA Table sizes in SAP PO

Question

Hello All,
We have SAP PO 7.4 deployed on SAP HANA SP 09, and the SAP PO is growing fast, and it grew by 200 GB over the last 2 days. The current size of the data volume is showing almost 500 GB just for the PO system. This is HANA tenant database installation.
The total memory used by this system show about 90 GB RAM.  However, I just don't how to get the list of the table with SIZE. I looked the view CS_M_TABLE, which is showing all the tables which are using the memory, but that does not still add up though. I need to get the list of all the physical table size so I can understand to see which table is growing fast and try to come with something that would explain why we are seeing about 500 GB of database size for a SAP Java PO System.
Thanks for all the help.

Hello,
As very simple bit of SQL that you can adapt to your needs.
select table_name, round(table_size/1024/1024) as MB, table_type FROM SYS.M_TABLES where table_size/1024/1024 > 1000 order by table_size desc
select * from M_CS_TABLES where memory_size_in_total > 1000 order by memory_size_in_total desc
It's just a basic way of looking at things but at least it will give you all tables greater than 1GB.
I would imagine others will probably come up with something a bit more eloquent and perhaps better adapted to your needs.
Cheers,
