Thank you Ludek. I had already read your wiki piece. Like I mentioned, the web service and data table have the same exact structure and what I am doing works perfectly on the development machine; it's only getting this error when I move it to a production web server (dev machine is Win7; server is WS 2012).
Perhaps one easy way for me to handle this quickly is not to change the data source type (always keep it as the web service for both report development and report run time) - but I do need to change some of the parameters of the web service URI string at run time, e.g. from "/Integration.svc/GetDataView/463/en/3/50" to "/Integration.svc/GetDataView/463/en/3/62" (only the last number changes). Could you please let me know the method or property to set to change the URI string for the XML web service data source (is it on the ReportDocument object?)? I haven't been able to find that anywhere. Thanks again, Richard.
