(email address removed by moderator)
Points to be covered
1) Why only SAP BW
2) What are the advantages of BW Reports
3) What is the concept of multi dimensional analysis of data in BW
4) How should an ideal BW Implementation should be...i mean what are the phases
Its'urgent

Answer 1

Hi Priya,
Please see this , it may help you.
(1) Why only SAP BW?
BW supports heterogeneous systems, where as other erp's and sap R/3 supports only homogeneous systems. Performance is also very much good. We can say BW a Decision Support System or Environment. History of data will be nearly 8 to 10ys. It records the data analytically where as the others or just transaction recordings.
(2)Advantages of BW reports
BW reports we can generate on internet, mobile and excel sheets. Where as the other erp's we can generate reports max on excel sheets only.
Its performance is good since, BW concentrates only on reporting.
(3)Multi dimensional analysis of data in BW
Infocubes have a max of 16 dimensions out of which 3 are predefined.
More data will be stored in dimensions,compared to flat structures. We can generate mini cubes(aggregates), specialising particular characteristics.
(4)BW implementation
There are 5 stages in implementation
one is collection of datan or preparation of data
second is identifying the end user (client's) requirements ie., defining the landscape
third is preparation of blue print
fourth is realisation
and last one is testing the entire implementation
Develop evaluation criteria and test plan(testing the entire implementation)
((For implementation in detail you can see this.
Preparation -
Identify the business requirements with the help of existing documents and business needs.
Basing on the requirements, determine which pre-delivered SD functional areas to be included.
Technical Requirements Planning like frequency of data uploads, events to be triggered (Process chains)
Identify the end user requirements ( BEx, Workbook, Crystal Report..) and security requirements.
Establish System Landscape and Transport Strategy (Basis).
Blueprint-
Set up of the Development environment .
Business Content Check : Finalize a list of pre delivered business content to be activated by functional components, data sources, info cubes, objects, queries, workbook and roles.
System Administration procedures like data access issues, definition of roles, responsibilities and tasks for each procedure.
Agree upon the instrument (template) to record the test result and additional requirements.
Develop evaluation criteria and test plan.
Coordinate with DBA for Table Spaces definition .
Testing of BW operating environment (both Plug-ins, BW backend and BW front-end).
Realization-
Business Contents Activation
Populate SAP delivered business contents with customer data
Verify the content activation Result
Data conversions and interface programs
Final Preparation-
Perform System Performance Tuning activities
Adjust database parameters
Review Indexes
Review data loading time and evaluate feasible options:
Parallel processing; partitioning; multi cube;
Review Query performance and feasible options:
Aggregation; compression; MultiCube;
Develop a BW Operations Guide
Final approval for going live
Support-
Go live Checks
Support review
Provide production support
Validate live business process results
Define the scope of next iteration of implementation.
