The bookings are created automatically by AbaNinja, but in your daily business you may have to make a entry yourself. You can do this under the menu item "Accounting > Account statement" or "Journal".
Documents can be added to the entry via the paper clip.
Fill in the required data and select "Enter" to complete the entry.
Note: If the Abacus connection is active, you must click on "Complete entry" when making the entry so that it will be transferred to Abacus.
