I am a B.Com fresher. Should I do SAP FICO in 2019?

This and this alone will take your path forward. If you go learning more tools, you will end up like a rat running inside a ferris wheel..(lot of hustle but going nowhere)..

Please dont go down that road. You are a commerce fresher, and companies prefer at least ICMAI or CA candidates for SAP FICO Roles. Sure there are a thousand guys willing to train you, but the opportunities now are far and few between. I would suggest you to stop worrying about learning software tools, SAP FICO/Oracle Apps/Hyperion these tools are waste of time right now.

Instead, you should focus on studying for a better higher accounting/finance qualification. Example, ICMAI/CA if you are good in accounting, ICSI if you not so good in accounting but can manage theory. You can also look at CFA credential (not ICFAI). This and this alone will take your path forward. If you go learning more tools, you will end up like a rat running inside a ferris wheel..(lot of hustle but going nowhere)..hope this helps..
