2. Business Blueprint
Check Business content against the requirements
Check for appropriate
Info Objects - Key figures & Characters
Check for Info cubes / ODS
Check for data sources & identify fields in source system
Identify Master data
document all the information in a file – follow standard templates
Prepare final solution
Identify differences (Gaps) between Business Content & Functional
specification. propose new solutions/Developments & changes if required at different levels such as Info Objects ,Info cube , Data source etc . Document the gaps & respective solutions proposed– follow standard templates
Design & Documentation
Design the ERD & MDM diagrams for each cube & related objects
Design the primary keys/data fields for intermediate Storage in ODS
Design the Data flow charts right from data source up to Cube .
Consider the performance parameters while designing data models
Prepare High level / Low level design documents for each data model.--- follow standard templates
Identify the Roles & Authorizations required and Document it – follow standard templates
final review of design with core BW users .
Sign off the BBP documents

3. Realization
Check & Apply Latest Patches/Packages ...in BW & R/3 systems.

perform Go Live checks as recommended by SAP in production system
keep up to date Patch Levels in Production system
Test for production scenarios in a pre-production system which is a replica of production system .
Do not Encourage the changes at this stage .
