The wsdl you provide is a WebService describing 5 different operations (GetArchiveReport, GetRawReport, GetReport, Map, Transform)
The wizard created a microflow using by default the 1st operation (GerArchiveReport), but based on your screenshots for the export mapping, you want to call the operation Transform.
This is why you got the error about the export mapping (for Transform) which doesn’t map the request body of the service (set on GetArchiveReport).
To fix it, open the properties of the WebServiceCall action in your microflow, and change the operation you want to call.
