Typical data distribution in SAP BW*
Comments: § 13-17% of system size
is reporting data § Temporary data is
subject to housekeeping (BALDAT, RS*DONE, ...)
§ HANA sizing report gives a 1st indication (OSS note 1736976)

A customer example - Randstad
CAUSE
Problem § System size is growing steadily
(35%+) § Some reports are used
infrequently § Several reporting solutions only
used temporarily
EFFECT
Situation § No classification of data into
important/unimportant § Data growth due to high
granularity of data § Long ETL runtimes regardsless
of several optimizations
