Axapta Layers

--
Dear Microsoft Team,

Can you provide me some links or some material about Microsot Axapta Layers?
And breif about what each layer is doing and how the layers are interacting
with other layers and how the data is flowing between eacg layers?

Check out the Technology section in Chapter 1 of the Ax Introduction course -

Check out the Technology section in Chapter 1 of the Ax Introduction course -
it has a great description of the layers and what their purpose is.

As far as how they interact - you can think of each layer, as you move out
from the center, as a descendent of the layer it encompasses (e.g. the
Address object in the USR layer is a descendent of the Address object in the
CUS layer, which is a descendent of the Address object in the VAR layer,
etc). This isn't exactly how it works, but covers the general principal.

There isn't really any data flowing between the layers.

Hope this helps.

Hi,Thanks for your reply.

Dear Connie,

Can you explain me briefly about the layers interaction or provide me some
URL`s about the application layers interaction.

If you do not already have the Introduction course material, you should be
able to find it on-line (I have a paper copy, so cannot provide a link easily).

There isn't really any interaction beyond inheritance.

Each layer as you go out from sys to usr can be thought of as a descendent
of the previous layer. The only difference is that all of the objects have
the same name and Ax works out the heirarchy.

A change made in a layer will be seen by all layers that extend the layer
that the change was made in (e.g. a change in the VAR layer will be seen in
the CUS layer and the USR layer).

In methods, the "super" keyword will execute the code in the previous layer.

Dear Connie,

I looked into the following link about the application object layers.

But here i found, what each layer is doing but i am not getting how each
layer is interacting with other layer.

I am looking into more functional and implementation wise. Based on your
discussion, i understood that each layer works independently. Am i right?

What exactly each layer contains. Each layer code is different or we are
doing customization on the system layer code?

Pleae provide me more in functional and implementation wise.

Hi Hanumanth,
Each layer code Inherits the basic code written on SYS layer by MBS Team.
After that depending on your Customers requirements and the Layer he has
License for you make the changes.
e.g. :
Your Customer has the license for CUS Layer, then all the development will
be done on this layer. Hence the file AxCUS.aod will contain the changes made
on CUS layer. This changes are not affected on SYS or any layer which is
below it. The changes will only be affected on CUS and USR layer will inherit
it.
Now you can make some changes on USR layer and this changes will only be
applied on USR layer and no layer below it. Hence the changes in USR Layer
will be stored in AxUSR.aod
You can give me your email id so that i can forward you a document with me
which explains Layer technology very nicely.

Hi all,

I need clear explanation about all the layers and what is the significance and purpose of each and every layer and how to get access for all layers except sys and usr.



Thanks in advance,
