Source -Seven's not always Microsoft's lucky number: Dynamics NAV 7 ERP delayed.
The number 7 isn’t lucky for every Microsoft team.
Microsoft has pushed back its delivery target for its Dynamics NAV “7″ by anywhere from a few months to a year, with final delivery now expected some time during calendar 2011 to 2012.
I first learned of the delay via a tweet from Rob Helm, an analyst with Directions on Microsoft. Microsoft officials confirmed that the next major version of Dynamics NAV, one of its four ERP products, is now tracking for 2011 to 2012.
