• ACCOUNTING_CLOSURES (6 keys): Accounting period closures, reopening periods, closing dates, comments.
• RUN_ACCRUALS (4 keys): Periodic accruals execution and status.
• INTEREST_RATE_CHARTS (29 keys): Interest rate chart CRUD, slabs, period types, annual rates, incentives, confirm deletions with {{id}}, {{product}}, {{rate}}, {{fromPeriod}}, {{toPeriod}}.
