Overriding Partitioning

If HASH partitioning is not suitable, or the capabilities of SUM regarding partitioning are not sufficient, you can override the partitioning settings applied by SUM.

Context

In DMO scenarios, the tables are already created during the uptime of the procedure, whereas the data migration takes place during the downtime for the application tables. As a consequence, the tables are empty when the SUM has stopped in the downtime dialog.

At that point in time, the content has not yet been migrated and the changes to the partitioning are not very costly. You can add or change the partitioning for application tables directly on the SAP HANA database while you are waiting in the downtime dialog of SUM, that is, when the Preprocessing roadmap step has finished and before you choose Next.

Procedure

Add or change the partitioning for application tables directly on the SAP HANA database, as described in SAP HANA Administration Guide chapter Partitioning Operations.
