Buss Objects is bought my SAP. It doesn’t mean that whole BI is going to change. But its good to learn BI + ABAP together. & If possible have knowledge of BO
Another perspective on this topic comes from SAP expert Axel Angeli on SearchSAP. Axel predicts that BO demand will outdo BI demand in the SAP marketplace.
who said that BO is replacing BI/BW this is just another conceptual mistake that has encompassed the market, BO is just a powerful BI tool the SAP BW platform is Netweaver, if I am wrong please tell me of any product in BO that creates cubes has a PSA or a DSO the only portion of BW that BO might replace is the Bex reporting tool provided within BW, SAP Netweaver BI 7.x is where the actual BW is and has always been even BO 4.0 does not have the storage concepts of Netweaver.
