(http://tfxz.files.wordpress.com/2014/03/naranjas.jpg)OnMarch25,inthecontextoftheHANA2014conference(hana2014.wispubs.com/Orlando/),thereisaspecialeventfocusingonBW7.4onHANA (http://bit.do/bw74launch).Preparingforthisevent,Ivereflectedonwhattotell,say,aBW7.0customeronwhyheshouldlookatupgradingandmigratingthatsystemtoBW7.4onHANA (http://scn.sap.com/docs/DOC35096).Fundamentally,Isee3majorreasons:
1. Itbecomessimpler.2. Itismoreflexibe(thanpreviousversionsofBW).3. Itperformsbetter.
SoletmequicklyjustifywhyIthinkthatthisisthecase.Pleasenotethatall theargumentsarebasedonthecombinationofBWand HANA.
It becomes simpler.
Modern modeling environmentThereisanumberofnewEclipsebasedmodelingeditors (http://scn.sap.com/community/netweaverbwhana/blog/2014/01/29/sapbwmodellingtools),e.g.forthecompositeprovider(https://scn.sap.com/docs/DOC52329) orthenewquerydesigner(https://twitter.com/tfxz/status/322677745937178624) (planned).Themodelingparadigmsareharmonized withthoseoftheHANAmodelerwhichmakesitacoherentmodelingenvironment,especiallywhencombiningBWwithHANAnativefeatures.
