Is there another mapping reference online other than the one provided in the resources here?

I was just wondering if I can find a broader mapping table to refer to in the future work if I ever encountered a PL account that was not included in the table provided here. Where can I find this? and what to do if one gets stuck on the mapping process when they don't know how to map a certain PL account item? Financial background is extremely necessary here I guess and it won't suffice for someone to learn the software skills if they don't have a good understanding of accounting and finance and the terminologies used in both. I hope the program can provide a course on that instead of just assuming we know all this financial vocabulary.
