CO-PA collects all the OLTP data for calculating contribution margins ( Sales, cost of sales, overhead costs)
CO-PA also has power reporting tools and planning functions however co-pa reporting facility is limited to
Integrated cross-application reporting concept is not as differentiated as it is in BW.
OLTP system is optimized for transaction processing and high reporting work load has negative impact  on the overall performance of the system.
In CO-PA we can configure structure of one or more operating concerns in each individual installation.
Actual Line Item table: CE1xxxx
Plan Line Items: CE2xxxx
Line Item Contain some information at document level that most cases is too detailed for analysis example  CO-PA Document Number, Sales document Number, Posting date.
CO-PA Maintains summarization of data used by all CO-PA functions like reporting, planning, assessments, settlements and so on.
Segment Table: CE4xxxx
The Characteristics that describes the market are first separated from the rest of the line Items.
Each combination of characteristic vales is stored in profitability segment number. The Link between the profitability segment number and characteristic values is maintained in Segment Table.
Segment Level: CE3xxxx
The Value fields are summarized at profitability segment and period levels and stored together with these fields in Table CE3xxxx.
This table contains total values of the period for each Profitability segment number.
We can compare an operating Concern associated by segment table and segment level to an Info cube. Info cube comprises Dimension Table Segment Table) and the fact table ( Segment Level).
Unlike Fact table the segment level key contains other keys like Processing type in addition to the key field from the segment table.
Characteristics in Info Cube corresponds to characteristics( Or Attributes) in Info Cube.
Value fields can be regarded as a Key Figures.
Summarization level in Operating Concern have the same function as aggregates for an Info Cube, the difference is that aggregates for Info Cube are managed together with the Info Cube Itself while summarization levels are updated at regular intervals usually daily.
Line Items in CO-PA is comparable with Operational Data Store
Characteristics from the segment table are the characteristics that are maintained in transaction KEQ3.
By Default all characteristics are selected.
When we generate CO-PA Data Source select accounting based option.
Fields KOKRS, BUKRS, KSTAR are compulsory.
There are no Characteristics available for line Items because accounting based data sources do not contain characteristics.
There are no value fields or calculated key figures available
KOKRS and PERIO must be selected as selection fields.
