I originally encountered this issue back in May with a customer.  We had another customer this month that had the same issue.  When you try to load an Excel Document with a Power View Report in it from SharePoint, you may encounter the default unable to load power view report image.

Before I get into specifics of the issue we had encountered with a few customers, I’d first like to say that you should validate that Silverlight is installed and working properly.  You may be able to do this by trying a standalone Power View (RDLX) Report outside of Excel. If you have check that and that is working, you may want to go through looking at the details presented in this blog post.

Unfortunately, the image above doesn’t really provide any real guidance as to what to do.  So, with any SharePoint issue, I go to the ULS log to see what is there.  Looking through the ULS log, there is error that stands out.  Nothing that shows an Exception of any kind.

You may or may not see the following entry:

Looking at a working system, we see the following:

There are two Properties that will get added to the SharePoint Farm Configuration for Power View.

InteractiveReportServiceUrl – This is the URL Pointer for Excel Services to redirect to the Power View page and render the Power View report.  If this isn’t present, then Excel doesn’t know what to do with the Power View Report that is within the Excel Workbook.

InteractiveReportApiUrl – This is a helper Javascript file for use with Power View.

These properties are part of the SharePoint Farm Configuration.  We can view these via SharePoint by looking at the properties of the SPFarm from PowerShell.

You can also see these via SQL via querying the SharePoint Config Database.

FROM [SharePoint_Config].[dbo].[Objects]
Where Properties like '%InteractiveReportServiceUrl%'

You won’t get a result back if the values are missing from the farm.  This is a quick way to tell if they are missing.  The Properties output in my farm looks like the following, when those values are present.

<object type="Microsoft.SharePoint.Administration.SPFarm, Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c"><sFld type="Int32" name="m_PersistedFileChunkSize">4194304</sFld><sFld type="Int32" name="m_XsltTransformTimeOut">1</sFld><sFld type="Int32" name="m_cPasswordChangeGuardTime">45</sFld><sFld type="Int32" name="m_cPasswordChangeMaxTries">5</sFld><fld name="m_PasswordChangeEmailAddress" type="null" /><sFld type="Int32" name="m_cDaysBeforePasswordExpirationToSendEmail">10</sFld><sFld type="Boolean" name="m_bUseMinWidthForHtmlPicker">False</sFld><fld name="m_EncodedFarmId" type="null" /><fld type="System.Collections.Generic.HashSet`1[[System.Int32, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089]], System.Core, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="m_serverDebugFlags" /><fld name="m_AuthenticationRealm" type="null" /><sFld type="Boolean" name="m_userLicensingEnabled">False</sFld><fld type="System.Collections.Generic.Dictionary`2[[System.Guid, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Version, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="m_Versions"><sFld type="Guid">3a9fdacb-c088-420d-9670-043c1417f6f2</sFld><sFld type="Version"></sFld><sFld type="Guid">66d56e1c-50b2-482e-af1a-7dd7ba0b72cc</sFld><sFld type="Version"></sFld><sFld type="Guid">00000000-0000-0000-0000-000000000000</sFld><sFld type="Version">15.0.4617.1000</sFld><sFld type="Guid">77e7f90e-1989-46c2-ad65-361a53dcb2e0</sFld><sFld type="Version"></sFld><sFld type="Guid">54d00007-0f81-42b1-8f06-fb9b981a617d</sFld><sFld type="Version"></sFld><sFld type="Guid">6ac833ea-3f8d-46b6-8b30-92ac4553a742</sFld><sFld type="Version"></sFld><sFld type="Guid">6371575d-8eae-41dd-903f-b9fbc2da7aad</sFld><sFld type="Version"></sFld><sFld type="Guid">c8a0b463-1852-4f3b-8fd3-216c4d19585a</sFld><sFld type="Version"></sFld><sFld type="Guid">42c6e513-ad52-4d28-93d6-d07d1afd7b14</sFld><sFld type="Version"></sFld></fld><fld name="m_UpgradeContext" type="null" /><fld type="System.Collections.Hashtable, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="m_UpgradedPersistedFields" /><fld type="System.Collections.Hashtable, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="m_Properties"><sFld type="String">WopiLicensing</sFld><sFld type="String">HostBIEnabled</sFld><sFld type="String">InteractiveReportApiUrl</sFld><sFld type="String">/_layouts/15/ReportServer/InteractiveReportAPI.js</sFld><sFld type="String">DisableIntranetCallsFromApps</sFld><sFld type="Boolean">True</sFld><sFld type="String">DisableIntranetCalls</sFld><sFld type="Boolean">True</sFld><sFld type="String">InteractiveReportServiceUrl</sFld><sFld type="String">/_layouts/15/ReportServer/AdHocReportDesigner.aspx?ViewMode=Presentation&amp;DeferredInitialization=true&amp;Fit=true&amp;PreviewBar=false&amp;BackgroundColor=White&amp;AllowSectionNavigation=false&amp;EnableKeepAlive=true&amp;AllowEditViewMode=false&amp;AllowFullScreenViewMode=false</sFld><sFld type="String">GuestSharingEnabled</sFld><sFld type="Boolean">True</sFld></fld><sFld type="String" name="m_LastUpdatedUser">BATTLESTAR\asaxton</sFld><sFld type="String" name="m_LastUpdatedProcess">psconfigui (3468)</sFld><sFld type="String" name="m_LastUpdatedMachine">ADMADAMA</sFld><sFld type="DateTime" name="m_LastUpdatedTime">2014-06-20T14:53:36</sFld></object>

So, what do we do if they are missing?  I was able to correct it by adding them back via PowerShell. Here are the PowerShell Commands for SharePoint 2013.

# Get the SPFarm object and list out the existing properties to verify
# the ones we are looking for are missing.
$farm = Get-SPFarm

# Set the Property Name and Value to add - InteractiveReportServiceUrl
$propName = "InteractiveReportServiceUrl"
$propValue = "/_layouts/15/ReportServer/AdHocReportDesigner.aspx?ViewMode=Presentation&DeferredInitialization=true&Fit=true&PreviewBar=false&BackgroundColor=White&AllowSectionNavigation=false&EnableKeepAlive=true&AllowEditViewMode=false&AllowFullScreenViewMode=false"

# Add the InteractiveReportServiceUrl Property to the Server Farm
$farm.Properties.Add($propName, $propValue);

# Set the Property Name and Value to add - InteractiveReportApiUrl
$propName = "InteractiveReportApiUrl"
$propValue = "/_layouts/15/ReportServer/InteractiveReportAPI.js"

# Add the InteractiveReportApiUrl Property to the Server Farm
$farm.Properties.Add($propName, $propValue);

# Propagate the changes back to the Database
# true to silently reinitialize the object with an existing object's data if the object already exists in the configuration store;
# false to throw an exception if the object already exists.

If the properties are there and are blank, or have the wrong value, you can do the following to update the existing properties.

$farm.Properties[$propName] = $propValue;

instead of

$farm.Properties.Add($propName, $propValue);

Once that is done, you’ll want to do an IISRESET on your servers for the Config information to get loaded.  Then try your Power View Report again and it should come up.

How does the configuration get into this state?  I don’t know for sure, but my thoughts are that it has to do with the order in which the Service Apps were installed.  If the RS Service was configured before the Excel Calculation Service, we may get into this state.  Regardless, the commands above should get it back into working status.
