Financial initial experience

I learned the most about the logistics module after getting started with axapt. After reading the logistics tutorial several times and analyzing the table structure and class structure of the entire module, it is not difficult to develop it, which of the following functions should be modified by the application consultant.
I have always been confused about the financial module, and I always think that finance is a very troublesome thing. In fact, the most important thing is that I have never been in touch with finance, even the accounting equations were only known the night before. although I have modified some financial services some time ago, they all follow the instructions of the application consultant. I don't know why I want to change it like that.
I wanted to keep an eye on the logistics industry. I couldn't help the technical consultant to understand all modules to make changes. Besides, the core of ERP is finance, so I don't need to mix it with ERP if I don't understand finance.
Starting from the day before yesterday, I began to take advantage of the principles of this accounting book, and may no longer find an accounting book that is more basic than this book. However, I am still confused by borrowing, and I cannot start with anything difficult, although it is not realistic to understand what the accounting major has for four years in a few days, try to have a concept as soon as possible.
I remember that in xingmengqiyuan starring Andy Lau, Feng Xiaogang had a classic line: "The unfortunate thing in life is that life cannot be re-initiated. The good news is that there is no need to re-invent it." This applies to my understanding of finance: "Financial Services only need to remember something, and difficult ones must also remember something ". compared with the logistics module, finance does not have much flexibility. You only need to set accounts for accounting, procurement, sales, and production, however, all business actions are reflected in the financial account. In most cases, problems are also discovered in the financial account, from the final balance or report analysis of a subject. the person with the most contact with maintenance after the launch is also the finance of the other party.
