In Microsoft Dynamics AX 2012 R3 CU8 environment, when I tried to to edit a report, I received the following message
AOT > Visual Studio Projects > Select a project > Right Click > Edit
Notice that VS 2010 is still being used as a default one.
Dynamics AX 2012 R3 still needs to integrate with Visual Studio 2010 and therefore you have to have BIDS (Business Intelligence Development Studio). You can use a SQL Server 2008 R2 or SQL Server 2010 SP2 installation image to install it (it’s one of the components you can select during installation of “A new standalone server or additional components” on the client machine.
Please follow below link for more details to get rid of this issue and add feature SSRS reporting services without report server configuration an existing SQL installation.
