Answer 1

Hi,
Start with Reports. What the client is using. What he is expecting.
If he got existing reports map the fields with Business Content BW Fields. Go to Business content and make a list of queries which are delivered from SAP. Explain them the KPI's. This should be good to start with. Also check the Tcodes they use.
Look for DataSources that get data from theses Tcode's.
Project Preparation (Initial stuff -- Do a conceptual review after this phase requirements gathering)
Collect requirement thru interviews with Business teams /Core users / Information Leaders.
Study & analyze KPI's (key figures) of Business process.
Identify the measurement criteria's (Characteristics).
Understand the Drill down requirements if any.
Understand the Business process data flow if any.
Identify the needs for data staging layers in BW – (i. e need for ODS if any)
Understand the system landscape.
Prepare Final Requirements Documents in the form of Functional Specifications containing:
Report Owners, Data flow, KPI's, measurement criteria's, Report format along with drilldown requirements.
Business Blue print (Functional spec-- Do a design review after this phase)
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
Realization ( Develop; Do a configuration review after this phase)
Check & Apply Latest Patches/Packages ...in BW & R/3 systems.
Activate/Build & enhance the cubes/ODS as per data model designs...maintain the version documents.
Identify & activate Info objects / Master data info sources / attributes, prepare update rules
Assign data sources .prepare transfer rules, prepare multi providers. Prepare Info packages.
Perform the unit testing for data loads….both for master data & transaction data.
Develop & test the end user queries.
Design the process chains, schedule & test
Create authorizations / Roles …assign to users..And test
Apply necessary patches & Notes if any freeze & release the final objects to quality systems
perform quality tests.
Re design if required. (Document changes, maintain versions)
Final Preparation ( QA and Other final stuff before moving to production, Do a performance Review after this phase)
Prepare the final check list of objects to be released .identify the dependencies & sequence of release 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.
Freeze the objects.
Go Live and support ( to production and support)
Keep up to date Patch Levels
Release the objects to production system
Run the set ups in R/3 source system & Initialize Loads in BW
Schedule Batch jobs in R/3 system (Delta loads)
Schedule the process chains in BW.
Performance tuning – on going activity
Enhancements - if any
