Hi All
I've found my answers:
1 - To do this am I going to have to drop the table first, then configure the Partition Criteria and then Provision the table into HANA again?
No you don't need to, just used an "Alter" Table and it can make the changes needed.
2 - If not, what might the SQL Syntax I would use to alter the table and add the new multi Level partitioning be?
This is what I used - Alter Table "<Schema>"."<Table>" partition by hash ("<field>") partitions 10, range ("<2nd field>") (Partition 'x' <= values < 'y') ...
3 - Would that be the same sysntax I would need to add into the SLT transaction IUUC_REPL_CONTENT to ensure the new partitioning continues?
Yes, except for the Alter Table part.
