The proper way is finding an accounting job that uses one of those systems and go from there. In conjunction with that, I would find a program (usually very expensive) that offers courses in those systems. I started in Deltek (similar to SAP/Oracle) years ago and was lucky enough to move around (within the accounting department) that I became very familiar in all aspects of the system and how it operates. We have also gone through multiple implementations moving from SAP into Deltek, Quickbooks into Deltek, and even moving/integrating payroll systems.
Learning the system is one thing but then actually implementing and configuring the system for a company is a whole other beast. The systems can be very complex and you of course want to set it up just right to get the most value out of them. It's A LOT of work and requires a TON of planning.
I'm sure there are ways to get around what I have said above (doing this for years) Maybe find an entry level position at a consulting firm working in SAP/Oracle? I say my way is “proper” because NOTHING beats hands on experience doing system implementations from within your organization. But plenty of people get hired with the “learn as you go approach” lol I don't mean to dog those people, but I have ran into WAY to many consultants that don't know what they are doing and it has cost my company a lot of time and money.
Good luck!
