The SAP HANA database offers a special time selection partitioning scheme, also called aging. Time selection or aging allows SAP Business Suite application data to be horizontally partitioned into different temperatures like hot and cold. The partitioning of tables that participate in Data Aging is administered on the ABAP layer (Transaction DAGPTM).
Partitioning needs to be done in each system individually as partitions are not transportable. Alternately, Partition Ranges can be maintained in customizing under SAP Netweaver > Application Server > Basis Services > Data Aging > Maintain Partition Ranges. Partition Objects must be defined to combine several tables that should be partitioned together according to the same schema (Transaction DAGPTC). Usually SAP applications suggest partitioning objects that can be applied.
All participating tables belonging to the data aging objects and enhancements must be assigned to a partitioning object. A table is assigned to exactly one partitioning object and cannot occur in more than one partitioning object. If the assignment of a table to a partitioning object does not fulfill customers’ requirements, they can create customer-specific partitioning groups without making modifications. Partitioning Groups override the assignment of tables to partitioning objects if a partitioning object as well as a partitioning group contains the same table.
The partitioning gets active only after the next Data Aging Run.
