BW is the information backbone engine for SAP and the mySAP landscape. Traditional R/3 reporting does a good job
of generating tactical (operational reports). But in the past few years SAP has growingly introduced the business information warehouse as the defacto reporting framework for the mySAP suite of solutions. Some reasons for introducing SAP BW:
a) An information warehouse that enables analytical reporting
b) In a typical SAP user community more than 70% of the users would be "read-only" or reporting users. It is unnecessary to provide SAP transaction system reporting to the 70%.
c) Ability to create reports on the fly providing much more flexibility to information insight.
The key components of BW that have gained momentum:
1) Strategic & tactical information analytics
2) Portal integration for extended and easier information consumption
3) Pre-delivered best business practices (Business content) for expedited implementations.
4) BW-BPS for planning and feedback into SAP transaction system
mySAP BW is the information engine for the new dimension suite of products like APO (demand planning), CRM (campaigns, trade and promotion management, customer churn analysis) and SRM (vendor scorecarding).
