SAP Extractor Connector uses the default formatting in the Thousand and Decimal separator for Qlik Sense
In Qlik Sense, the thousands and decimal separator must be set as comma and point by default (as shown below), while using the SAP extractor connector, to avoid a non-automatic conversion of values, when a field for instance is a CHAR (255) that contains floating point numbers.
SET ThousandSep=','; SET DecimalSep='.'; SET MoneyThousandSep=','; SET MoneyDecimalSep='.';
