1.When setting up GL accounting coding in an accounting information system, why would it be helpful to use a systematic and rational account coding structure e.g. 4,000 series for assets, 5,000 series for liabilities? Why would it be better to use 4 digits (i.e. 1,000's) in the coding vs only 3 digits?

2.What role does corporate finance (FP&A or financial planning and analysis) play in the GL close process? Why would the accounting and FP&A team meet to review the trial balance by account code?
