Add transactions to journal

I want to ask 2 tough question.

  1. In the Ledger there is icon “+” in the upper right corner which gives possibility to add “New transactions”. So far so good. I can choose accounting journal - that’s OK and there is a empty field call “Document number” - Can that document number be filled automatically? And
  2. Can the transaction be added not only in the Ledger but in the respective journal to see it in the list of the transactions for reporting and audit purpose.
