Why would you need to implement SAP BW?
! Because… BW is now recommended by SAP as THE tool for reporting on operational data contained in SAP R/3
! Because… BW is more and more often positionned (by SAP) as THE « necessary » interface to true information delivery
! Because… You’ve been told you should first use what’s available in house
! Because… You *must* implement SAP BW
SAS can help as well !
