有SAP Finance and SAP business intel 經驗的朋友請進

I heard SAP Finance is on Functional side and SAP BI is on Technical side. What is difference between Functional side and technical side in term of learning? Technical side needs any programming skill? For both SAP FI and SAP BI, do they need any prerequisite? I do not do much pure accounting work but run a lot of financial reports. Which module should I learn?

I do not have any programming skills.

Thanks so much!
