Microsoft Dynamics AX 2009 Service Pack 1 (SP1) contains the complete set of updates that Microsoft has issued since the June 2008 RTM release of Microsoft Dynamics AX 2009, as well as a number of enhancements and new features to improve the product’s functionality and user experience.
NOTE: The majority of these fixes are specific to individual modules or workflows, and as such should not require a full re-evaluation cycle of Microsoft Dynamics AX 2009 SP1 at sites where the RTM version of the product is already under evaluation. Only incremental testing in the relevant areas may be required.Other key highlights in this service pack release include:
The SP1 package updates rather than replaces the Microsoft Dynamics AX 2009 RTM installation. In order to install SP1, the RTM version of Microsoft Dynamics AX 2009 must already be installed on your system.
