title: How to edit XML query for SSRS 2012 RDL
body: <p>I need to modify the query of an RDL that is using a shared data source. I'm only familiar with setting up datasources for reports in Visual Studio for Business, with an embedded datasource. When I open the RDL in VS and look at the dataset's properties, "Use a shared dataset" is selected and below that the dataset is listed with a URL. When I go to that URL I am able to navigate to the datasource name and it displays as XML in IE. I have no idea where to go from there - how to modify the query. This is for SQL Server 2012 and I can only find MS articles for the latest versions - not even for 2014.</p>
  
  <p>We believe that the client created this report on their own in Report Builder (which I have never used - again, I've just worked with reports in VSB), so is that the only way to modify this?</p>
