I've got a project with over 100 reports in it. Some of these reports date clear back to SQL 2005 while others are as new as last month.
Within this project, I've got one report which has 8 sub-reports (the sub-reports make up substantially all of the content, other than page header/footer).
Simply opening the report with the SQL 2016 report designer in VS 2015 and then deploying it to SSRS results in a report where 3 of the 8 sub-reports no longer function, each providing the very useful message:
One or more parameters were not specified for the subreport, 'subreportName', located at: /Path
Of course, nowhere in that message does it say which parameters, nor is anything recorded on the server identifying the parameters, nor are there in fact any parameters that are missing or invalid.
I've tried innumerable combinations ranging from deleting the subreport entirely and re-creating it, supplying only the parameters that don't have defaults on one extreme, to passing values to all 15 report parameters, including hidden ones, including parameters that have defaults. All of the values being passed are valid (far as I can tell) and yet this error insists on appearing.
Again, these reports worked before the SQL 2016 designer touched them.
Any ideas? I've already wasted days trying to make this latest version of the report designer behave.
