In this section, you make system settings for Information System
reports that use summarization. Using summarization, you can update
and evaluate (report on) a summarized database. There are several
advantages to using summarization:
Drilldowns that access the summarized database have better
performance than reports that do not use summarization.
Data from other decentralized systems can be part of the
summarization database. These other systems can be other SAP R/3
Systems, SAP R/2 Systems or non-SAP systems.
