Rechnungen

Die Endpunkte dieser Endpunktberechtigung finden Sie im Controller "AccountancyInvoiceReceipt".

Um Eingangsrechnungen erfassen oder abrufen zu können, muss die Endpunktberechtigung "Belegsystem Eingangsrechnung erfassen" aktiviert werden. Um Ausgangsrechnungen abrufen zu können, muss die Endpunktberechtigung "Belegsystem Ausgangsrechnung lesen" aktiviert werden

Der Eingangsprozess für Rechnungen wurde vollständig überarbeitet. Aus diesem Grund werden für den neuen Eingangsrechnungsprozess neue Endpunkte benötigt. Nach vollständiger Umstellung aller Kunden werden die alten Endpunkte abgekündigt und entfernt. Die Umstellung erfolgt in Abstimmung mit unseren Kunden und Partnern, soweit uns diese bekannt sind.

Die OPENWOWI Sandbox wurde bereits für die Verwendung des neuen Eingangsrechnungsprozesses vorbereitet. Der alte Eingangsrechnungsprozess kann auf dieser Instanz nicht mehr verwendet werden.

Die Endpunkte der Version 1.2 sind momentan in der Entwicklung und können noch Änderungen erfahren.

Hinweise zur Funktion

Informationen zu Rechnungen können ebenfalls im Abschnitt "Belegsystem" und im "Auftragswesen" gefunden werden. Aufgrund der sehr individuellen Buchungsarten und Konten-Strukturen sollte die Art der Rechnungsübermittlung immer vorher mit dem Kunden besprochen werden. Die Datenstruktur der Rechnung orientiert sich am Aufbau einer XRechnung. Bitte beachten Sie zudem, dass noch nicht für alle Zusatzkontierungen Endpunkte verfügbar sind. Zusatzkontierungen ohne existierende Endpunkte werden derzeit nur eingeschränkt unterstützt. Die Zuordnung von Zusatzkontierungen ist zudem nur möglich, wenn der vollständige Kontenrahmen und die Buchungsvorschriften bekannt sind.

Rechnungen erfassen (alter Eingangsrechnungsprozess)

Hinweise zur Funktion

Die Daten zum "PaymentMeansCode" wurden dem XRechnung-Format entnommen. Eine Tabelle der gültigen Codes finden Sie unten auf der Seite.

Die Beträge in der Node "Lines" sind ausschließlich Nettobeträge. Hierbei gilt:

BaseAmount ./. LineDiscountAmount ./. LineWitholdAmount = LineExtensionsAmount

Die API prüft, ob alle Beträge in Summe übereinstimmen. Hierbei wird auch ein Abgleich zwischen Brutto- und Nettowerten vorgenommen.

Bitte beachten Sie, dass die API bereits in der Lage ist, mehr als zwei unterschiedliche Steuer-IDs im "Lines" Knoten zu berücksichtigen. WOWIPORT erlaubt derzeit allerdings nur zwei unterschiedliche Steuer-IDs.

Wenn Sie nur einen Steuersatz "U0" oder "V0" im Knoten "Line" übermitteln, dürfen Sie den Knoten "TaxTotal" nicht mitsenden, da keine Steuer anfällt.

Die Übergabe eines Auftragsbezuges erfolgt, anders als die übrigen Entitätzsbezüge, nicht in dern "References". Die Zuordnung erfolgt hier über die OrderReference (jeweils pro Rechnungszeile oder für die gesamte Rechnung).

Wenn Sie eine "OrderReference" übermitteln, brauchen Sie die "Line" nicht mitzusenden. Diese werden aus dem Auftrag entnommen, wenn Sie "OrderReferencesAllLines" = "true" setzen. Bitte beachten Sie, dass der Auftragswert exakt mit dem Rechnungswert übereinstimmen muss.

Die "InvoiceDocumentId" darf nur verwendet werden, wenn das WOWIPORT DMS (d.velop) aktiv ist. Hier wird die Dokumenten ID aus d.velop eingetragen. Eine fehlerhafte Verwendung des Feldes kann zu Folgefehlern in der Rechnungsverarbeitung führen.

Rechnungen erfassen (neuer Eingangsrechnungsprozess)

Hinweise zur Funktion

Die Daten zum "PaymentMeansCode" wurden dem XRechnung-Format entnommen. Eine Tabelle der gültigen Codes finden Sie unten auf der Seite.

Die Übergabe eines Auftragsbezuges erfolgt, anders als die übrigen Entitätzsbezüge, nicht in den "References". Die Zuordnung erfolgt hier über die OrderReferences. Es können mehrere Aufträge verknüpft werden.

Innerhalb der Lines haben Sie dann die Möglichkeit, die "Commission Items" aus den aus den Aufträgen mit den jeweiligen Rechnungspositionen zu verknüpfen. Dies erfolgt über die OrderReferenceLineId.

Die "InvoiceDocumentId" darf nur verwendet werden, wenn das WOWIPORT DMS (d.velop) aktiv ist. Hier wird die Dokumenten ID aus d.velop eingetragen. Eine fehlerhafte Verwendung des Feldes kann zu Folgefehlern in der Rechnungsverarbeitung führen.

Der neue Eingangsrechnungsprozess ist dafür ausgelegt, auch unvollständige Rechnungen (eRechnungen) verarbeiten zu können. Aus diesem Grund werden die Rechnungen immer in dem maximal möglichen oder dem gewünschten Bearbeitungsschritt angenommen. Sollten also fachliche Fehler in der Rechnung bestehen, so wird diese zwar angenommen, aber der Status kann abweichen. Sie können den Status im Response unter "CurrentStep" sehen.

Elektronische Rechnungsformate (neuer Eingangsrechnungsprozess)

Hinweise zur Funktion

Um sowohl eRechnungen im XML Format, als auch Rechnungen im PFD Format mit angehängten XML Dateien verarbeiten zu können, wurde der Endpunkt als reiner Datei-Upload konzipiert. Informationen über die Encodierung und die Hashwertbildung finden Sie unter "Dokumente und Medien".

Hinweise zur Funktion

Mit diesem Endpunkt können Sie Verbrauchs- und Energiedaten zu einer Rechnung hinzufügen. Der zusätzliche Endpunkt ist notwendig, da die elektronischen Rechnungsformate die Verbrauchstdaten nicht in ihrem Standard-Schema berücksichtigen.
