I am working in a MNC for the last 4 years in account receivable process. I m 27 yrs old and now i want to do SAP FI course from Siemen. I am a b.com hons grad with less than 50% marks. So please advise if i go for SAP FI will it help my career in long run as i hv got less percentage in grad will it be any problem for me to get a job in top companies (Like TCS, Wipro, IBM).
