The projection of the data frame projects the layer on the fly just for viewing. But the data of the layer remains unchanged. So it has no effect on the result. If you use the geoprocessing service in WAB and draw point on the map, the spatial reference of the point is Web Mercator. You can use GeometryService to project it to the proper spatial reference before send to the geoprocessing service. ... View more
