I thought this text was a good little read in reference to basic reporting in AX 2012 (i.e. via SSRS and Visual Studio). It takes you through developing a series of example reports in very comprehensive steps.
If you have a developers install of AX 2012, Reporting Services and Visual Studio, then you can follow along with this book to get yourself started with report development. Note: without access to the applications for playing on, I do not think you would get much out of the book, as it is only hands on (very minimal concept, explanation for just reading).
A fairly light read, as far as developers text books go, which I found quite refreshing. Worth a look for beginners, or those wanting an easy start on AX 2012 reporting.
