SSRS report definition is newer than Server - sql-server

Question

I created some reports in Visual Studio 2015 with all the latest updates. However, when I try to deploy the reports I get this message:
The definition of this report is not valid or supported by this version of Reporting Services.
11:40:28 Error
The report definition may have been created with a later version of Reporting Services, or contain content that is not
11:40:28 Error
well-formed or not valid based on Reporting Services schemas. Details: The report definition has an invalid target
11:40:28 Error
namespace 'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' which cannot be upgraded.
The first lines of the .rdl file are set up like this:
<?xml version="1.0" encoding="utf-8"?>
<Report MustUnderstand="df"
xmlns="http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition"
xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner"
xmlns:df="http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition/defaultfontfamily">
Can I change the schema definition? If so, to what? I tried just changing 2016 to 2014 or 2012, but neither worked.
Is there a place I can go to see valid definitions?

Answer 1

I actually ran into a similar problem where a change I needed to make resulted in an "Undocumented Error/Invalid RDL Structure" error in 2016, so I edited the RDL file so I could open it in an earlier version and make my changes. Not too hard, but you need to make a couple of tag edits.
For new reports you should probably just use an older version, but for existing reports you can do this: (I reverted to 2008)
Change the Report tag:
Remove MustUnderstand="df"
Change the xmlns value to "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition"
Delete the xmlns:df attribute.
Delete the entire "ReportParametersLayout" block.
Delete the "df" tag and its content.
Delete the "ReportSections" and "ReportSection" opening and closing tags (not the content).
Actually wrote some superhackish code to do this as part of a blog post, but the manual edit is simple enough.

The settings below should be set to your sepecific version of SSRS, and then take the RDL from the \bin directory
Or, after updating the TargetServerVersion, simply use right click | deploy from the rdl.
The accepted answer is significantly more difficult/prone to error/unlikely to work across multiple versions of ssrs, and needs to be applied each time you change the rdl.

I had the same issue when switching to VS2017 and installed Report Designer Version 14.2.
For me only 3 steps needed to fix the issue.
1: Set Change the xmlns to "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition"
2: Remove ReportSections" and "ReportSection" (Only Tags).
3: Remove report ReportParametersLayout section.
The only thing you need to memorize is to point xmlns to 2008/01
Other 2 steps can be seen in the error message after you change to 2008/01 and try to run the report.

Answer 5

I recently ran into this issue as well. I found that I only needed to change two items in the .rdl file in question.
Change FROM:
Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner"
TO:
Report xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner" xmlns:cl="http://schemas.microsoft.com/sqlserver/reporting/2010/01/componentdefinition" xmlns="http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition"
Unlike other responses, I needed 2010 instead of 2008. I would check an .rdl file that you have already deployed.
Remove the "ReportParametersLayout" block.
Note: If I removed ReportSections block, it did not work as others have noted.

Answer 6

I ran in to same problem and this is how I solved it,
Set the "TargetServerVersion" property on report project properties to be your old version of reporting server.
Build the project.
Get the report in the bin folder and deploy to the old reporting server.
Your source reports format and namespace will be updated to latest version. But bin folder reports will be build to be compatible with targeted reporting server version.

I have automated this task.
create a form with a textbox named "TextBoxFile" and a button.
In the code of the click button:
Dim xmlDoc As New XmlDocument()
xmlDoc.Load(TextBoxFile.Text)
Dim root = xmlDoc.DocumentElement
For Each elel As XmlNode In root.ChildNodes
Debug.WriteLine(elel.Name & " " & elel.NodeType)
Next
If root.Attributes()("xmlns").Value <> "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" Then
root.Attributes()("xmlns").Value = "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition"
End If
Dim nsmgr = New XmlNamespaceManager(xmlDoc.NameTable)
nsmgr.AddNamespace("bk", "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition")
Dim autoRefreshElements = root.GetElementsByTagName("AutoRefresh")
While autoRefreshElements.Count > 0
root.RemoveChild(autoRefreshElements(0))
End While
Dim ReportParametersLayout = root.GetElementsByTagName("ReportParametersLayout")
While ReportParametersLayout.Count > 0
root.RemoveChild(ReportParametersLayout(0))
End While
Dim ReportSections = root.GetElementsByTagName("ReportSections")
If ReportSections.Count > 0 Then
' Move content of ReportSections just below the block.
Dim ReportSection = ReportSections(0).ChildNodes()
' First, copy the elements after
Dim precedent = ReportSections(0)
For Each child As XmlNode In ReportSection(0).ChildNodes
Dim clone = child.Clone
root.InsertAfter(clone, precedent)
precedent = clone
Next
' After deleting the existing block
While ReportSections.Count > 0
root.RemoveChild(ReportSections(0))
End While
End If
xmlDoc.Save(TextBoxFile.Text)
MsgBox("Ok")

The most simple and straight forward solution. I would suggest you to find Microsoft.ReportingServices.ReportViewerControl.WebForms in Manage NuGet Packages of the current project and update this dll version to latest version.
Navigate from VS menu: Tools > NuGet Package Manager > Manage NuGet Packages for Solution
