About license codes and configuration keys

Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012

When you purchase Microsoft Dynamics AX, all functionality is included. By default, some features and functionality that you do not use may be enabled. The administrator should disable the features that are not needed by disabling license codes and configuration keys.

When a license code or configuration key is disabled, the associated module or feature is removed from the user interface. Large sets of functionality, such as modules, are controlled by license codes. Many license codes, in turn, enable configuration keys that allow you to enable and disable functionality at a more detailed level.

License codes can be enabled or disabled in the License information form. (Click System administration > Setup > Licensing > License information.) Configuration keys can be enabled or disabled in the License configuration form. (Click System administration > Setup > Licensing > License configuration.)

Microsoft Dynamics AX uses a fixed database schema, which means that related data is not removed from the database when a configuration key is disabled. Be aware that enabling, disabling, and then re-enabling a configuration key may cause gaps in the data.


Features that are specific to a country or region are enabled and disabled based on the primary address of the legal entity. For more information, see Create or modify a legal entity.

For more information about a specific license code or configuration key, see the License code and configuration key reference.

For more information about licensing in Microsoft Dynamics AX 2012, see the Pricing and licensing guide and the Software licensing terms.
