Hi
We have a HANA table (VBFA) which we have drastically reduced, as it was taking up most of the Memory. The rowcount was reduced from 540240655 to 40958378, but the table is still consuming 128 GB of RAM in memory, this did not reduce with the cleanup.
See output of script HANA_Tables_LargestTables (thanks to SAP note 1969700)

Please advise on what we need to do to reduce the memory usage of this table.
Thanks
