To export bookings, you need an BookingExport instance with an array of records. Example:

export =
  'Herkunft'        => 'XY',
  'Exportiert von'  => 'Chief Accounting Officer',
  'Berater'         => 1001,
  'Mandant'         => 456,
  'WJ-Beginn'       =>,1,1),
  'Datum vom'       =>,2,1),
  'Datum bis'       =>,2,28),
  'Bezeichnung'     => 'Beispiel-Buchungen'
) # For available hash keys see /lib/datev/base/header.rb

export << {
  'Belegdatum'                     =>,2,21),
  'Buchungstext'                   => 'Fachbuch: Controlling für Dummies',
  'Umsatz (ohne Soll/Haben-Kz)'    => 24.95,
  'Soll/Haben-Kennzeichen'         => 'H',
  'Konto'                          => 1200,
  'Gegenkonto (ohne BU-Schlüssel)' => 4940,
  'BU-Schlüssel'                   => '8'
} # For available hash keys see /lib/datev/base/booking.rb

export << {
  'Belegdatum'                     =>,2,22),
  'Buchungstext'                   => 'Honorar FiBu-Seminar',
  'Umsatz (ohne Soll/Haben-Kz)'    => 5950.00,
  'Soll/Haben-Kennzeichen'         => 'S',
  'Konto'                          => 10000,
  'Gegenkonto (ohne BU-Schlüssel)' => 8400,
  'Belegfeld 1'                    => 'RE201802-135'
