+# UpdateTrackingCodes
+
+
+
+## Description
+
+Dieses Programm liest eine Excel-Datei mit Sendungsnummern ein. Anhand der Lieferantenbestellnummer (LB-*****) wird der zugehörige Auftrag ermittelt.
+
+Handelt es sich um einen Auftrag vom Otto Marketplace (kShop = 7), wird eine Rücksende-Sendungsnummer bei DHL generiert. Dies erfolgt durch den Aufruf (per exec) eines dafür bereitgestellten Programms.
+
+Bei Aufträgen von anderen Marktplätzen wird derzeit keine Rücksende-Sendungsnummer benötigt.
+
+Anschließend werden die relevanten Daten in die JTL-Datenbank geschrieben. Das Versanddatum wird dabei für alle Aufträge gesetzt – mit Ausnahme der Aufträge vom Otto Marketplace. In diesem Fall wird das Versanddatum erst eingetragen, nachdem die Versandinformationen über ein externes Programm an Otto übermittelt wurden.
+
+### Executing program
+
+```
+node index.js
+```
