7.12 SUMMARIZATION LEVELS IN CO-PA
To satisfy various business needs, CO-PA deals with large data to produce
segment reports, i.e., reports based on customer hierarchy, product group, or
geographical location. Due to the large volume of data handling, the user may
question system performance. To increase response time, the SAP R/3 system
provides a summarization concept in CO-PA.
Summarization means the system aggregates data based on required
segments and stores the data in a different set of tables. Since the system holds
data in summary form in different tables, it provides quick access to the user.
When the user runs a particular CO-PA report, the system looks for the
most suitable summarization table instead of the CE1XXXX table (where XXXX
is the operating concern name).
In the absence of the summarization level, the system always looks for
CE3XXXX and CE4XXXX tables for each and every run. A summarization level
stores the original dataset in a reduced form.
From a technical point of view, a summarization consists of two tables
that have just been generated, the key table and the totals table. The key table
corresponds to the segment table and contains the pseudosegments produced
from the reduced characteristics. The totals table corresponds to the segment
level and contains the associated value fields.
Figure 7.6 shows the summarization levels. From top to bottom, it goes
from more specific segments to less specific segments.
