I am planning to learn SAP BW. When i started searching, i am confusing with so many various words like BW, BI, BW on HANA, BW/4HANA.
Can somebody explain which one should i target as a beginner. Are BW, BI BW4/HANA are different from each other. If i learn SAP BI...do you think i can still work in BW4/HANA.
Any additional inputs on materials and certification are really helpful.
