Manager doesn’t allow accounts under the Cash on Hand and Cash at Bank tabs to be adjusted by Journal.
Bank/Cash accounts track the movement of actual money - deposits (receipts) and payments. Journal’s relate to non-monetary transactions as no actual money is being moved.
With Bank accounts, if journal entries were permitted, reconciling with the Bank Statement would be impossible, as the Bank could never have any knowledge that the journal existed - Banks only have knowledge of your monetary deposits and monetary payments.
Therefore it would be impractical to allow Journals and also have bank reconciliations.
