Can anyone tell me the difference between Table 50 “Accounting Period” and Table 10560 “Accounting Period GB”

Accounting Period is general table for setting up accounting period and Accounting Period GB contains United Kingdom local functionality.

Do both tables need to have period records for a UK company?
