We have many layers like sys,usr,cus,var,hfx,etc in Dyanmics Ax.If we need to develop a new module(like HumanResource),in which layer we had to develop that module?.
Follow best practices. See this link: http://msdn.microsoft.com/en-us/library/aa851164.aspx
If you are an AX customer you should use CUS layer.
If you are implementing for a client you should use VAR layer.
If we had developed a module in USR layer.Can we able to move objects from USR to CUS layer.It is possible,then how ?.
That's quite easy ram. All you have to do is export the entire development as .XPO and open the environment in Cus layer and just import them. You are done.

If we are moving object from one layer to other how the lables are handeled?.can u give me some idea?
not required to move label files. They work without any change if the label file is available.
So labels wont have impacts on layer is it so?
What is :-license code and its uses?
I think it is difficult to explain all this in the forum.
