Bookkeeping core

SKR03 and SKR04 are both there, I can switch charts and existing bookings migrate automatically, and the monthly lock with a timestamped protocol gives me a real period close. But I found no public information on manual journals, opening balances, cost centres or accruals — and the business year is fixed to the calendar year with the calendar month as the booking period. A solid mid-level ledger, none of the accountant's extras shown.

Real double-entry is confirmed — 'Für einfache und doppelte Buchführung' plus trial balance, cashbook, depreciation, and cost centres/BWA in Pro, which is past the EÜR-only tools. But nothing on SKR03/SKR04, opening balances, journals, or a period close with locking, so I can't credit it beyond the mid anchor.
