Error publishing SSRS Report in Dynamics AX 2012 Enterprise Portal

Question

Good morning.
I have a problem ad i'll appreciate so much your help. I made a SSRS Reporting project with Business Intelligence Development Studio (through the template "Business Intelligence --> Report Server Project). Once deployed to report server, the report
successfully works. I Want to publish this report in Dynamics AX 2012 Enterprise Portal, through the web part "SQL Server Reporting
à SQL Server Reporting Services Report Viewer", but when i select the .rdl file from the list, i receive the following error:
An error occurred during local report processing.
An error has occurred during report processing.
Cannot create a connection to data source 'DataSource1'.
An attempt has been made to use an unregistered data extension, 'OLEDB-MD'. To use this data extension, it must be registered in the Web.config file of this Web application.
I've Checked the config file and the specified handler is correctly set. I read in a forum that the problem may be caused by the fact that the database of the report server is set as "Native" instead of "Sharepoint Integrated". Is it
possible? just in case, there's the possibility to display a ssrs report in EP in "native mode"?
Thank you so much in advance
Simone

Hi Katherine.
Thank you so much for your reply. You understood perfectly what I mean. I followed the instructions in the document, but the installation of te .cab file won't work. I tried with the Sharepoint Management Shell and with STSADM.EXE, but in both cases i receive
an error like this:
PS C:\> Install-SPWebPartPack -LiteralPath "C:\Program Files (x86)\Microsoft SQL
 Server\110\Tools\Reporting Services\SharePoint\RSWebParts.cab" -GlobalInstall
Confirm
Are you sure you want to perform this action?
Performing operation "Install-SPWebPartPack" on Target "C:\Program Files
(x86)\Microsoft SQL Server\110\Tools\Reporting
Services\SharePoint\RSWebParts.cab".

I checked the directory and the .cab file is in the right position. Am I doing something wrong?
Thanks a lot in advance.
