Dynamics AX 2012 - how to delete a layer

With the advent of model management in Dynamics AX 2012, Microsoft has gotten rid of the ax.aod files which in previous versions of DAX constituted the layers.
In DAX 2012 adjustments for the meta data model and code are stored in the modelstore in the database.

In previous version deleting a layer containing adjustments to the standard application consisted of delete the ax.aod file and synchronizing and compiling.

How is this done in DAX 2012 ?

The answer is a command-line tool called AxUtil.

To delete e.g. the usr-layer in the application do the following:

1) Shut down all AOS-servers but one (applicable only if you have more than one AOS running).
2) Go to command line interface on the server where the last AOS is running.
3) Go to the folder where DAX's management utilities are placed, e.g.
    C:\Program Files\Microsoft Dynamics AX\60\ManagementUtilities
4) Run the Axutil like this:
    Axutil delete /layer: /db:

    To delete the usr-layer in the MicrosoftDynamicsAx database:
    Axutil delete /layer:usr /db:MicrosoftDynamicsAx

    Below an example is shown:
   

5) Restart the AOS
6) Start the DAX client.
7) In the process of starting up, DAX will detect that something has happened with the modelstore, and prompt you with:


    Choose the action appropriate for your situation.
8) Start the remaining AOSes.

    Hi Jacob,

    Is it possible to use this method to delete customisations that were deployed via an .xpo? For instance we are now trying to remove "DynamicsConnectorR2.xpo" from the application.

    The only recommended way has been to open the project that was deployed from the .xpo and delete the usr items one at a time.

    Thoughts on any quicker methods?

    Cheers!

    Dillon

      @dillon.bailey it is not possible to remove those XPO customization imports like that and opening the deployed project is most likely your best bet. Unless you managed to deploy it to the USR layer for example while all of your customizations may be in the CUS layer...but that is unlikely.

    hello, it is raising error "login failed for user ...".
    Although I am running it through an admin account.

Suppressing the infolog

Supressing the infolog is often useful in D365FO when augmenting code. When augmenting code using COC (Chain Of Command), you can have new code run either before or after the code you are augmenting. This means that any infolog-messages that the standard application code does, will be shown to the user, even if your augmentation supports a scenario where there must be no infolog-messages. How do you avoid the standard application infolog-messages ? To the rescue comes temporary supression of the infolog. The suppression consists of: 1) Saving the current infologLevel 2) Setting the infologLevel to SysInfologLevel::None 3) Run your code 4) Restoring the saved infologLevel to the infolog For example a table could have a validatewrite-method that validates that you are only allowed to use 3 out of 6 options in an enum-field, and you need to allow for a fourth one. Table a - validateWrite method: boolean validateWrite() {     Switch (this.enumField)     {     ...

Indicating mandatory field in a dialog (RunBase) class.

A classical problem is indicating that a field is mandatory in a dialog, when the field is not bound to a datasource/field in a datasource. Normally fellow developers will tell you that, that is not possible. I found a way to do this. In your Runbase-based class you can implement the putToDialog-method e.g like this: protected void putToDialog() { super(); fieldMask.fieldControl().mandatory(true); } where fieldMask is a DialogField object in your dialog. This will make the field act like it was a mandatory field from a datasource in a form, showing a red-wavy line under the field, and requiring the field to have a value. Attention: Your class has to run on the client.If you set your class to run on the server, you get a run-time error, when the fieldMask.FieldControl()-call is made.

Dynamics ax 2012 traversing selected records in a form data source

A classical developer challenge in Dynamics AX is to enable a form button when multiple records have been selected in the form by the user. This usually involves writing some form of loop (for or while or do-while) that starts out with calling _ds.getFirst() and continuing the loop as long as _ds.getNext() returns a tablebuffer. Well things got a little bit easier in AX 2012. In AX 2012 you can use the MultiSelectionHelper class. One example is the following that I encountered in AX 2012: Can you make the customer collection letter print out run for each selected collection record in the Print/Post collection letters form (Accounts receiveable / Periodic / Collections / Print/Post Collection letters). If we ignore the possibility for setting up print destination for running each report we can do this in two steps: 1) Change the "Multiselect" property of the "MenuButton" and the "Menuitembutton" in the MenuButton in the form from "Auto...
