The default setting for the unload priority for SNP Outboard™ tables is defined as 9. The unload priority sets the priority of the table to be unloaded from the memory. The value can be 0–9. The value 0 means the lowest unload priority and 9 means the highest unload priority. The most commonly used unload priority of the tables stored in the memory is 5, which means if you need to free up some memory space, the archived data will be unloaded to the disks rather than keeping it in the memory.
A setting is available to allow you to define the unload priority other than the default value. In the Nearline objects tab of SNP Outboard™ with Storage Management, when running on SAP® S/4HANA settings, the option Unload Priority of Archive Table is available. This option allows you to define the new unload priority value.

Set unload priority for table on HANA
All archived data is divided into SAP® S/4HANA partitions based on the NLS request ID using range partitioning. Range partitioning creates dedicated partitions for certain values or certain value ranges. Range partitioning is used to actively manage the partitioning of a table. Partitions can be created or dropped individually.
