 Blue Yonder Supply and Demand API. This tool has no schema information and therefore does not

@@ -110,8 +78,46 @@ As this tool does not provide any schema validation, it is important to note tha
 Any typo in the parameter `category` or the header column of the csv-file is directly translated into the
 dedicated XML-tag, leading to potential errors when attempting to process the XML-file further.
