SAP HANA-optimized InfoCube The SAP HANA-optimized InfoCube is a
standard InfoCube that is optimized for use with SAP HANA. When
you
create SAP HANA-optimized InfoCubes, you can assign
characteristics and key figures to dimensions. The system
does not create any dimension tables apart from the package
dimension however. The SIDs (master data IDs) are
written directly to the fact table. This improves system
performance when loading data. Since dimensions are
omitted, no DIM IDs (dimensions keys) have to be created.
The dimensions are simply used as a sort criterion and provide
you with a clearer overview when creating a query in
BEx Query Designer.
Inventory Management with SAP HANA-Optimized InfoCubes
For InfoCubes with non-cumulative key figures, the different
types of data are loaded separately (initial non-
cumulative, historical transactions and new deltas). You need
two data transfer processes (DTPs) for this:
A DTP to initialize the non-cumulative data. Go to your DTP's
Extraction tab, under Extraction Mode, and
choose Initial Size for Non-Cumulative Values.
A DTP to load data and historical transactions:
o For new deltas, go to your DTP's Extraction tab, under
Extraction Mode, and choose Delta.
o If historical data is supplied by the source, go to your DTP's
Update tab and choose Historical Transactions.
Note
A DTP can be changed in a production system if the development
class of the imported DTP can be changed.
You then just need to change the settings in the DTP and
reactivate it. For more information, see 1558791 .
This logic replaces the compression logic (and therefore the
associated marker update) for the SAP HANA-
optimized InfoCube. There is no semantic basis for compression
with SAP HANA-optimized InfoCubes. The data is
only compiled. Markers are not updated.
Prerequisites
You are using an SAP HANA database.
Constraints
If you are using an SAP HANA database, you can only create SAP
HANA-optimized InfoCubes. You can continue
using existing standard InfoCubes that do not have the SAP
HANA-optimized property or you can convert them.
The property Data Persistency in BWA is not available in SAP
HANA because the SAP HANA database assumes
the role of primary persistence.
