Get ready for AX 7 Dev Intro Certification!

Hello DAX DEV,

I took the exam MB6-890 last year Jun 2017 and, in my opinion, if you are an experienced AX2012/09 developer,  You will need to study diligently some concepts that I will be mentioned here in this post. But I don’t think the exam is too complicated if you worked with the older versions of AX you’re probably familiar with at least 40%+ of the exam’s content, things like  X++ Code flow Read & write, Security Objects and some core falimiar transaction tables & classes did not change, and they will be mentioned, so it’s worth taking a look again.

If you are not familiar with the older versions and  you wish to take the exam, I’d advise you to take the Full MS course.

Although the most recognized tables & classes structures barelly changed in this new version, there are some major changes in the whole architecture of the ERP, many new tecnologies are involved. there’s a completelly different way of deploying and maintaining the development, might take a while to get used to, but in practice it is simple.

Considerable diferences when developing for AX2012 & AX07

First and most important change for us developers is the new environment [IDE], that is completelly on Visual Studio, with many new functionalities, with t new way of deploying and tranfering code between environments.

Changed & Extinct concepts: 3 concepts were completely revised.

1. There are no more XPO’s files [Check ax07 Deploy]
2. No more Morphx [Check Form Patterns]
3. No more X++ Jobs(*) .

(*): If you want to do execute some specific code, you’ll need to create a class with a main method , place your code  in the main method and set the class as the default startup Object of your project and set your project as start up project of your solution, then run the solution, which will execute the class. [Check links: 1. Getting started   & 2. Debugging without a startup object]

New Concepts

Microsoft was very wise when building this new ERP,  All code was remastered in order to be in accordance with the most recent implementation norms & patterns. The objects extensions allow the developer to alter objects appearence & behavior by adding code to extension files, without changing the Original source file, In run time both the Original File and all the overlayering extentions will be read. This new architecture facilitates merges, HotFixes, MS updates and protects SYS code.

Important concepts  to study, (what I believe to be the most important):

1. Models and Packages. (Deploy & Import processes, no more XPOs)
2. Overlayering Extensions.
3.  Form Patterns.

A good knowledge of these 3 topics will come handy not only for the exam but also to avoid problems with deployments once you’re developing. So invest some time to fully grasp the whole concept.

Apart from the MS online material, I studied other sources. Here are all 8 helpful links:

1 – Brief outlook of the exam.
2. MBS Parter Course. (Full MS course, A valid MS credential is needed)
3 – X++ Code Flow.
4 – Form Patterns.  (Usefull post to understand the new form design architecture)
5 – Customization overlayering extensions.
6 – Microsoft Doc About Models.
7 – Microsoft Doc About Projects.
8 – Packages, models, and projects. (Succinct and direct info)
