A manual journal that touches a control account is refused at posting, with the reason named. The refusal protects one agreement your accountant relies on absolutely: the control account in the ledger must equal the detail in its subledger — debtors in the books equals the sum of what customers owe, invoice by invoice.
A journal has no invoice, no customer, no warehouse movement underneath it. Let one through and the two figures part company, with nothing on either side to say which is right. So corrections to debtors, creditors or stock never travel by journal: they travel by the document that owns the detail — a credit note, a payment, a stock adjustment — and the control account follows on its own. Journals remain free to move money between every ordinary account, which is what they are for.
