I have been working in BO Data Services for sometime now for ETL and Data Migration stuff. As the assignments involved did not follow SAP line of products entirely, hence reporting tool had not been SAP BI one. Now in SAP Reporting side, I find a lot of products that are being used - like WEBI, BW, Xcelsius, Crystal reports and many others. Could someone tell me if there is any relation between them and where can I start from.
I have heard and seen some guys from another team working on universe and creating reports out of it. I am trying to follow them but still if someone could give a headstart about how different BI products are related and where from could/should I start from, it would be helpful.
