Reporting Services Reports that contain Bing Maps seem to broken due to a change in the Bing Map APIs. From the initial analysis, Bing Maps SOAP web service seems to be shut down after July 31, 2017.
When we access the Bing Maps API from SSRS we are calling into this method http://dev.virtualearth.net/webservices/v1/imagery/contracts/IImageryService/GetImageryMetadata, and are receiving this message: “The service method is not found”.
Please note, SSRS Product Team is aware of this issue and are working with the Bing API Team.
