Opening Balance Initialization is intended for scenarios where a new reporting currency or secondary ledger must begin with initialized balances rather than full transactional history. The feature is compatible with balance-oriented implementations because the objective is to establish beginning balances in the target ledger or reporting currency. Therefore, Balance level is compatible. Adjustment only level is also compatible because the secondary ledger is maintained through manual or adjustment entries rather than a full automatic transaction copy. Subledger level and Journal level involve detailed accounting transfer from the primary ledger or subledgers, which is not the purpose of opening balance initialization. Currency level is not a valid secondary ledger data conversion level in this context. This matches Oracle’s ledger architecture for thin secondary ledgers and balance-based reporting currencies.
