I want to say general journal entries not show cash on hand category for debit and credit transaction
You cannot enter cash or bank transactions in Manager with journal entries. You must do this in the Receipts & Payments tab. Read these Guides:
But why i want to this option because all entries save at once journal entry,
for example a/c receivable, a/c payable,
Both debit and credit of a receipt or payment are saved at once when you enter those transactions. For example, on a payment, the credit goes to the cash or bank account from which it is made. The debit goes to the expense account you choose on the entry form. It is the equivalent of a journal entry, but frees you from having to figure out which account is debited and which is credited. Manager determines this from the context.
