Hi ramesh,
We are using the non layered approach for BW/BI implementation. Currently approximately 90 -95%
implementations are done using non layered approach. We are fetching data from SAP and Non-SAP source system. We are doing data cleaning and transformation by applying the business logic in Transfer rules. Finally data at detailed level or line item level will be loaded to ODS. Data at slightly summarized or highly summarized level will be stored in Info cube.
Reporting is done from this Info cube. Detailed reporting is done from ODS
Please find the below document.
Thanks,
Phani.
