What is ODS (Operational Data Store) SAP BW/BI?
‘Operational Data Store’ or ‘ODS’ is used for detailed storage of data. It is a BW architectural component that appears between PSA ( Persistent Staging Area) and infocubes, it allows BEX (Business Explorer) reporting. It is primarily used for detail reporting rather than dimensional analysis, and it is not based on the star schema. ODS (Operational Data Store) objects do not aggregate data as infocubes do. To load the data into an IDS object, new records are inserted, existing records are updated, or old records are deleted as specified by RECORDMODE value.
