Answer 1

Hi,
One of the Document(TBW45) has explored the comparission like below:
SAP BW-BPS:
1) Loose Integration with the transactional data flow
2) Fast and simple adaptation to current and future organizational changes
3) Free and unrestricted definition of integrated planning scenarios.
4) One homogeneous planning environment for the flexible design of different planning steps.
5) More simulative planning processes
6) One central data warehouse as basis for all information needed in the  decision process.
SAP R/3 :
1) Close link to the transactional data flow
2) Organizational changes have immediate effects to the transactional data flow (only limited changes are possible)
3) Plan integration is a sequential process which follows predefined planning steps.
4) Heterogeneous predefined planning applications, which are optimized to the needs of specific planning steps.
5) More determined planning processes.
6) Unstructured mass data from transactional processes.
