In BWonHANA BW
systems there was a new object introduced. It was SAP HANA-Optimized DataStore Object. I mentioned it in my blog post
related to BWonHANA
- Benefits
of #BWonHANA. It was a type of DSO object that was optimized for HANA DB. This
objects do not have any data in its change log table stored persistently. The
change log table is calculated on the fly via HANA’s calculation view. Data is
read from the history table for the temporal table of active data in the SAP
HANA database. The tables around the optimized DSO comprises of a history table
main table and delta table. The object contains additional field IMO__INT_KEY
in the active data table. The field is pure technical and it is not visible in
reporting.
While migration
of the BW system to HANA DB the DSO is needed to be migrated to optimized one. It
can be done via t-code RSMIGRHANADB.
As of BW 7.3
SPS09 this type of DSO became obsolete. Conversion to SAP HANA-optimized DSO is
performed automatically for all standard DataStore objects. Conversion of the
DSO objects to the SAP HANA-optimized objects is thus obsolete. It is possible
to use the SAP HANA-optimized DataStore objects, but SAP recommends to
reconverting them back to original DSOs. That can be done via report RSDRI_RECONVERT_DATASTORE.
