How to fix duplicate reports with double underscore (__) in Configuration Manager

The other day, I was running the ConfigMgr reports in my lab, especially the asset intelligence reports for some hardware information.

I tried to run the first report __ Hardware 01A – Summary of computers in a specific collection, it did not run successfully.

The following is the error code.

The report server cannot process the report or shared dataset. The shared data source 'AutoGen__5C6358F2_4BB6_4a1b_A16E_8D96795D8602_' for the report server or SharePoint site is not valid. Browse to the server or site and select a shared data source. (rsInvalidDataSourceReference)

Based on the error code, the issue could be related to the shared data source. So when I checked data source properties for the report, it has no value configured in it.

The shared data source reference is no longer valid.

To fix this, click on the select a shared data source, select {5C6358F2-xxx}, click on Ok.

Run the report now, it works fine.

Likewise, I run another report, it also had the same issue. This report also starts with a double underscore (__)

So I have searched with the first report to see if any duplicates. I got 2 entries.

Based on this, I figured out, the reports with a double underscore (__) are duplicates of the original and might have happened during the upgrade of the Configuration manager site (2103).

Since the configuration site in my lab was upgraded to 2013 followed by the latest hotfix a few months ago, the logs are overwritten hence cannot find the root cause.

For now, I will need to figure out, how many reports are duplicated with a double underscore (__) and get rid of them (delete them).

The following is the SQL query for it.

Use ReportServer;
Select ItemID,Path,Name,ParentID,Type,Description,Hidden,CreatedByID,CreationDate,ModifiedByID,ModifiedDate,Parameter 
FROM dbo.Catalog
 WHERE Type = 2
 and name like '[__]%'
 Order by Name

The following is the SQL query to get a list of reports without double underscore (__).

Use ReportServer;
Select ItemID,Path,Name,ParentID,Type,Description,Hidden,CreatedByID,CreationDate,ModifiedByID,ModifiedDate,Parameter 
 FROM dbo.Catalog
 WHERE Type = 2
 and name not like '[__]%'
 Order by Name

Before we take delete action, we can do a quick comparison (VLOOKUP/excel) to confirm these __ reports are duplicated or not.

There are about 250+ reports which have the same symptoms and these can be deleted.

Now, how do we remove these duplicate reports? Deleting one by one by going to each category based on the SQL data?

We can make sure of the PowerShell script to delete these reports in one go.

The following is the PowerShell script from the Technet forum.

Hope this helps!

  1. OPS! If somebody did blindly follow, they would be in trouble because the first SQL query should NOT NOT NOT include not in "...and name not like '[__]%' Order by Name..."

    It must be:

    and name like '[__]%' Order by Name
