Hi, I currently work in mainframe technology. i want to learn something new so planning to learn a different technology and work in it in future. i am currently working in mainframe (tech role) for about 9 years now with an automotive background. I have got a suggestion from colleagues to learn BW and then BW with HANA as there could be good demand in future. Now, Are BW and BW with HANA separate courses? Is it workable to learn both of these in parallel?
My advise is get expertise in BW and later go for BO and HANA Courses Thanks Madhukar
