Demo Company Overview
The Demo Data set for Microsoft Dynamics® AX 2009 is no longer based on the Global Trade and Manufacturing Company. Based on market feedback we have created a new Contoso Entertainment systems group of companies. It comes with 2 fiscal years of transactional data that enable us to demo our stronger Business Intelligence story and Role Center pages, while allowing us to easily expand the demo data story in future releases as we expand Microsoft Dynamics® AX’s functionality footprint.
Contoso Entertainment Systems (CES) is a home electronics manufacturing, distribution and retail company that includes a Professional Services department. Its headquarters are in the USA with a key distribution subsidiary based in Germany and it works with the relevant currencies. CES distributes televisions, projectors, Digital Video Recorders and Players, and audio receivers. It manufactures speakers and assembles home theatre systems. CES’s customers are primarily based in North America and Europe and include Major Accounts (such as hotel chains), Wholesalers (of differing sizes), Retail stores (that are self-owned and operated), as well an internet storefront.
The legal and physical structure of CES is setup as follows:
· CEC – Contoso Entertainment Consolidation, based in USA
· CEU – Contoso Entertainment USA, Headquarters based in USA
o Site 1: Production of all speakers
o Site 2: Assembly of home theatre systems and Services
o Site 3: Production of Standard speakers
· CEE – Contoso Entertainment Europe, Distribution subsidiary company based in Germany
o Site 4: Distribution, Assembly and Service of all products
· CVC – Virtual company that includes table collections from CEU and CEE.
The downloads for Contoso Entertainment Systems demo data offers transactional data for Basic, Administration, General Ledger, Bank, Fixed Assets, Accounts Payable, Accounts and Receivable, Inventory Management, Intercompany, Production, Master Planning, CRM, Project, Expense Management, and Human Resources modules, and is intended to demonstrate these modules’ functionality. It also offers base data (i.e. no transactions) for the Product Builder modules. There is no demo data available for Payroll and Cost Accounting modules.

About a milestone ago I announced SQL AOD. Since then it has been quite quiet on my blog - for two reasons 1) I've been heads down in new features and 2) I've been on paternity leave. Now the completion of M2, the next milestone of AX "6", is within reach and I've returned to my office. This means I can share some more exciting news.
Since the days of AOD files are numbered we need a new vehicle for deploying metadata elements to an AX installation. To address this need we introduce Models. A model is a containment of metadata elements.
To create a model you use the new command line utility AxUtil:
This will create a new model with the name "My Model" in the USR layer. This new model can be selected in the AX client configuration utility as the default model. When you start AX the status bar will tell you which model you are currently working in - just next to where the current layer is shown. When you make changes in the AOT, like overlayering elements, creating new elements, changing X++ code etc., the resulting elements will automaticaly be contained in your model.
When you have completed all your changes, then your model is complete. In other words it is time to move the model from your developer box to a production system. In AX2009 you would copy your AOD files - with models you need to export it to a physical file. Again you will use AxUtil:
Now you can copy this file to the production system and import it there:
You can even uninstall it again - if that is what you want. This is semantically the same as deleting an AOD file in AX2009:
So far I have described the model capabilities that gives parity with AOD files: We have a file based container that can be xcopy deployed and we can delete models again.
From what I've described so far models aren't much different than layers and AOD files. They are; and provide some highly desirable capabilities - which will be the topic of a near-future post - so stay tuned.

If you, like anyone else, want to get your hands on R2 – here are the links for customers and partners.
R2 is an incredible engineering achievement. Let me mention just one remarkable improvement: We have collapsed all GLS layers into the SYS layer. This means that for the first time you can have one instance supporting local requirements in 41 countries simultaneously. Learn more here. I’m proud to have been part of the team making it happen.
With any great product launch a lot of material is made available. That is also true for R2 – and yet something stands out. In collaboration with Microsoft Studios a number of short videos have been created. I think they are truly amazing – what do you think? Try out the links below.

4 layers have been renamed in Dynamics AX 2009 . DIS / DIP / LOS / LOP have become HFX / SL1 / SL2 / SL3 respectively. HFX is reserved for releasing hot fixes, and the 3 new solution layers (SL1/SL2/SL3) will be used to release Microsoft Dynamics Industry Solutions.
The purpose of having 3 solution layers is to enable side-by-side install of Industry Solutions. At deployment time any SL1 layer can be renamed to SL2, SL3, BUS or BUP through a regular file rename. The AOS will recognize the layer, and honor its position in the layer stack. This will enable installing up to 3 Industry Solutions on the same system (or up to 5 Industry Solutions if the BUS and BUP layers are vacant.)
Another aspect of side-by-side installation is conflicting names and IDs in the model. The AX platform requires unique names and IDs of all model elements, we will ensure uniqueness across Industry Solutions through our engineering processes. Naturally there will be logically overlayering conflicts for certain elements; but as the Industry Solutions by nature are verticals we anticipate very few of these. These conflicts will need to be resolved; one way is to reclaim one of the SLx layers as an adaptation layer. More information on this will be available as the Industry Solutions become available.
Why not just support an unlimited numbers of layers?
Frequent feedback we get is to add more layers; and open them up for consumption by the partners. And heck, why we are at it why not have an unlimited number of layers?
Currently; there is an upper limit on the number of layers the kernel can support. This number is 16. The technical explanation has to do with referencing of the elements in the model. Each model element is stored in a record in the AOD file. The RecId for model elements is a 32 bit integer. 4 of these bits denote the layer; the remaining 28 bits are used to calculate the offset into the AOD file where the record is located. In version 3.0 (and previously) the block size was 1 byte. This basically mean the maximum size of an AOD file is about 256MB (2^28). In version 4.0 we moved this limit by denoting one of the 28 bits to control the block size. When the bit is not set, the 27 bits is the direct offset in to the file. When the bit is set, a block size of 48 bytes is used to calculate the offset in the file. This enables AOD files with sizes up to about 6.5 GB (2^27 * 48), while enabling binary backwards compatibility with 3.0 AOD files (with sizes less than 128MB (2^27)).
If we decide to use one bit more to denote the layer (giving us 32 layers); it means we are only backwards compatible with AOD files with sizes less than 64MB (2^26). As that is not acceptable; tools to align the contents in AOD files would be needed. For 6.0 we are investigating options to tear down these limitations once and for all.
In my first two posts on models in AX (Part 1 and Part 2) I covered the deployment specific behaviors of .axmodel files - it should be apparent we introduced .axmodel files as a deployment replacement for AOD files. In the process we added some nice capabilities like a manifest and signing. The real benefit of models, and the ultimate reason we are adding this level of abstraction is because:
You can have as many models per layer as you want.
Let us examine this statement. In AX2009 a layer is the confinement unit of model elements. The layer is the unit of which you can export, deploy and delete model elements. (Here I'm deliberately ignoring the capabilities provided by XPO files, as these are suitable for development purposes only, and not deployment.) In AX6 this limitation has been removed, that means you can segment your layer into as many models as you like.
Here are a few examples where this could be useful in development scenarios:
Let's examine the statement a bit deeper. There are two ways of getting a model: Either you create one on your own, or you receive it from someone else. If you can have as many models as you want per layer, it also means:
You can deploy models from several sources into the same layer.
Here is an example: You are a customer and would like to install two ISV solutions that both are available in the BUS layer. In AX2009 you would have a tough choice to make: Either you picked your favorite solution and learned to live without the other one, or you invested in having the two solutions merged into one layer. This merge is technical challenging, and a costly affair once updates to either solution are being released. In AX6, however, you download the two models, and use AxUtil to import them. When a new version of either model is released, you simply use AxUtil to update the model.
This all sounds too good to be true, what is the downside? There is one limitation to what a model can contain:
An element can only be defined once per layer.
This means that two models containing a definition of the same element cannot be installed in the same layer. For example; if the two models both contain a class named: "MyClass" they will not be able to install side-by-side in the same layer. Model elements have two alternate keys, they are: [Type, Parent, ID] and [Type, Parent, Name]. Each layer can only contain elements that can uniquely be identified via the two alternate keys. In less technical terms, this means that two elements of same type under same parent (or without a parent) cannot co-exist if they have same name or same ID. For example: A table cannot have two fields with same name, or two fields with same ID. Another example: You cannot have two display menu items with the same name.
There are three ways you can be hit by this limitation:
So apparently we cannot guarantee that models can co-exist in the same layer - so what are the options when two models are in conflict? When you import a model that conflicts with an already imported model, you get three options:
Models enable a lot of highly desirable scenarios, one of the most important scenarios being that models from different sources - for example, two ISVs - can be installed in the same layer side-by-side. There are a few technical limitations; but the risk of conflicts is much reduced in AX6 and even when conflicts occur there is a less-expensive way to make the models co-exist.
More on models...
Dive deep in to the architectural details of Microsoft Dynamics AX to make relationships clear and development tasks easier. The first part of the book is aimed at consultants and developers who are new to Microsoft Dynamics AX but have backgrounds in business application development using traditional languages, frameworks, and tools. It describes the architecture and development environment and explains key application frameworks that developers need for their customization, extension, and integration projects. The second part of the book is a reference guide for developers who work with Microsoft Dynamics AX deployments, with information on developing new functionality and supporting users. It covers more complex development concepts such as advanced forms and reports, reflection over the application metadata, performance, upgrades, migration, and setup. This is the first book written by the Microsoft product group architects and the first to take developers deep inside Microsoft Dynamics AX.
Inside Microsoft Dynamics 4.0 is now available for download at: http://download.microsoft.com/download/2/5/8/258C8894-B94A-4A87-81EA-4DBB9776F8F2/622579eBook.pdf
Today we built the first official build of Dynamics AX ever that does not run on AOD files. Starting today Dynamics AX's model database is stored in a Microsoft SQL Server database.
Seen from within MorphX you hardly notice the difference. Everything works as it used to; there are no new feautures; but yet it feels different. The responsiveness of MorphX has slowly been deteriorating as the number of elements in the model has grown over the last releases. Today the speed is back. Navigating the AOT is suddently a pleasure again. Meta data heavy operations, like searching, completes an order of magnitude faster. For example; searching all methods on forms for any text completes in 2 seconds.
But wait a minute; AOD files were not just a database, they were also a deployment vehicle - what is the replacement? Dynamics AX supports a new file format: axmodel-files. (extension: "axmodel", example: "AxSYS.axmodel"). These are binary files, and provides the same deployment capabilites as AOD files did - and yet they are less than half size. Using a new tool you can import/export axmodel files to/from SQL. You can also import AOD files into SQL.
So far we have aimed at providing 1-to-1 parity with AOD files; but the potential of this is amazing - I hardly know where to start...
To night we celebrate this major achievement with the team.

Updated 30-06-2012 official beta version available here: http://informationsource.dynamics.com/RFPServicesOnline/Rfpservicesonline.aspx?ToolName=Microsoft+Dynamics+AX+2012+Combine+XPO+Tool+Beta+1.0
Updated 14-01-2011 to support UniCode XPO files. Notice the change in parameters.
So now you are using version control - and you just realized the master is no longer the AOD layer file, but instead a zillion of XPO files. Still you want to provide an AOD file to your consumers, as that is the way to deploy an AX application.
Page 96 in Inside Dynamics AX 2009 contains a description on how to build an AOD file from XPO files. In this section an SDK and a tool are mentioned. While we are working on providing you with the SDK for building a layer file, I can make the CombineXPOs.exe tool available.
See the attached file.
Usage: CombineXPOs.exe -XpoDir XPOfolder -CombinedXpoFile DestinationFile.xpo -utf8
Example: CombineXPOs.exe -XpoDir USR -CombinedXpoFile myFile.xpo
Files in the XPOFolder folder must match the AOT structure. This is automatically ensured when using AX version control integration.
In my first post on AX models I showed that models provide parity functionality with AOD files. Models goes several steps further, and addresses some of the shortcomings of AOD files. Have you ever been in a situation where you had several AOD files, but couldn't quite remember which was which, and where they came from? Models solve this problem by containing a manifest. A manifest contains attribute values describing the model.
AX models support these manifest attributes:
NameName of the model.
Display NameFriendly name to be presented in user interfaces.
DescriptionA longer text describing the model.
PublisherPublisher of the model, e.g. “Microsoft Corp.”
Version NumberFour part version number, e.g. 184.108.40.206.
Source LayerID of the layer from which this model was exported and hence target layer during import.
The manifest can be inspected for models in the model store by using AxUtil:
To modify a model's manifest you can use AxUtil:
Now we have a model with a manifest. This mean we can track structured information about the model. The next thing you want to do is to ensure the receivers of your model file can trust the model - or at least be able to judge if the model comes from a trustworthy source. To achieve this you can sign the model. We support two ways of signing a model. Strong name signing and Authenticode signing. Here is a post that explains the details and use scenarios of each.
Strong Name Signing
When you are importing a strong name signed model; you are guaranteed the model file hasn't been tampered with since it was exported. To strong name sign an model, you need to use the Strong Name Tool: SN.exe to generate a key pair file. When you export your model to an .axmodel file you can specify the key to sign the model with:
If you are a publisher of models, like an ISV that provides models e.g. for download, you should consider authenticode signing your model. If you do, then your customers are guaranteed the file hasn't been tampered with, and that you created the model.
When you are importing an authenticode signed model; the model's publisher is authenticated. Depending on the certificates, the model is either imported silently (if the publisher is one you trust), or you will be prompted to ensure you trust the publisher. If the model isn't authenticode signed, you will always be prompted (to accept importing a model where the publisher can't be authenticated).
To authenticode sign a model file you need to export it first using AxUtil. After this you use the SignTool to perform the actual signing.
The features around deployment and manageability of models by far exceed what was possible for AOD files. Having this solid foundation enables many new scenarios and drives down TCO. It is also a solid foundation for us to add more capabilities. For example; dependency management between models is high on our list of things to consider next.
You might have realized this already, an .axmodel file is a managed assembly. This means you can use tools like ILDASM to peek inside it.
