==General==
The layer system in Dynamics AX is an important feature for customization. Every element in the [[AOT]] has to be defined at a certain layer. There are 8 layers available in Dynamics AX. For each layer exists an additional patch layer. Each layer can be seen as a overall partitioning of the system. The layers also define a range of IDs for elements created at this layer.

* SYS (System) 1-8000
* GLS (Global Solution) 8001-16000
* DIS (Distribution) 16001 - 18000
* LOS (Local Solution) 18001 - 20000
* BUS (Business Solutions) 20001 - 30000
* VAR (Value Added Reseller) 30001 - 40000
* CUS (Customer) 40001 - 50000
* USR (User) 50001 - 60000

You have to buy licence codes to get access to a certain layer. Typical customization layers are BUS and VAR. If you don't have a license code for a higher level, you are working per default on the user layer.

==Customization==
One of the greates features in Dynamics AX is that an element can be defined a multiple layers. The system takes always the element from the outermost layer. In contrast to normal development where you modify the original code, your overlay an element from a deeper level on a higher level. So it is still existent but not visible for the system. All you customizations are therefore on one layer, like VAR or BUS. That makes distribution of your solution as easy as possible. You just take the complete VAR layer and plug it into another application. This can be done by copying the corresponding file.
