Finding objects marked for deletion

During our code upgrade we have identified that the SysDeletedObjects configuration keys were still turned on. Also many DEL_-prefixed fields were being referred or used in various places. We had to come up with a way for finding objects marked for deletion.

The documentation gives you an idea of what to do with such elements.

https://docs.microsoft.com/en-us/dynamicsax-2012/appuser-itpro/delete-obsolete-application-objects

https://docs.microsoft.com/en-us/dynamicsax-2012/developer/best-practices-tables

The following job can produce a CSV file, which contains everything with the DEL_ prefix, their table property and layer information:

static void findDelObjectsinAOTTree(Args _args)
{
    #Properties
    #AOT
    int row;

Modifying D365FO metadata using reflection

As part of our code upgrade to Dynamics 365 Finance and Operations we have removed some processes, for which the security roles had to be refreshed en mass. For this I have decided to go with modifying D365FO metadata using reflection to see how can we do it with the new file-based repository.

modifying D365FO metadata using reflection

First I have created a new C# project and referred the following 3 Dynamic Link Libraries from the AOSService\PAckagesLocal\bin folder:

Microsoft.Dynamics.AX.Metadata
Microsoft.Dynamics.AX.Metadata.Core
Microsoft.Dynamics.AX.Metadata.Storage

Then the following code was developed, which shows how to manipulate the metadata using the new DiskMetadataProvider classes. In the example below we were working against the JADOperation package and AxSecurityRole objects.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Dynamics.AX.Metadata.Storage;
using Microsoft.Dynamics.AX.Metadata.Core.Collections;
using Microsoft.Dynamics.AX.Metadata.Providers;
using Microsoft.Dynamics.AX.Metadata.MetaModel;
 
namespace ModifyAOT
{
    class Program
    {
        static bool removeNode(
            AxSecurityRole _role,
            KeyedObjectCollection<AxSecurityPrivilegeReference> _privs,
            string _node
            )
        {
            bool isModified = false;
 
            if (_privs.Contains(_node))
            {
                Console.WriteLine("Removing " + _role.Name + "." + _node);
                _privs.Remove(_node);
                isModified = true;
            }
 
            return isModified;
        }
 
        static void Main(string[] args)
        {
            string packagesLocalDirectory = @"C:\AosService\PackagesLocalDirectory";
            IMetadataProvider diskMetadataProvider = new MetadataProviderFactory().CreateDiskProvider(packagesLocalDirectory);
 
            var l = diskMetadataProvider.SecurityRoles.ListObjects("JADOperation");
            var le = l.GetEnumerator();
 
            while (le.MoveNext())
            {
                bool isModified = false;
 
                AxSecurityRole r = diskMetadataProvider.SecurityRoles.Read(le.Current);
                KeyedObjectCollection<AxSecurityPrivilegeReference> privs = r.Privileges;
 
                isModified = removeNode(r, privs, "JADCCDelayCaptureBatchProcess") || isModified;
                isModified = removeNode(r, privs, "ProfitAccountStatistics_CustItemGenerate") || isModified;
                isModified = removeNode(r, privs, "CCMOrderPadLoginManagementMaintain") || isModified;
 
                if (isModified)
                {
                    ModelSaveInfo model = diskMetadataProvider.ModelManifest.ConstructSaveInfo(diskMetadataProvider.ModelManifest.GetMetadataReferenceFromObject("JADOperation", "AxSecurityRole", r.Name).ModelReference);
                    diskMetadataProvider.SecurityRoles.Update(r, model);
                }
 
            }
 
            Console.WriteLine("Press any key to continue...");
            Console.ReadKey();
        }
    }
}

And this is all that you require for modifying D365FO metadata using reflection.

You can find some other use cases of doing metadata reflection in previous blog posts as well:

FormDataSource display methods must be static

During our Dynamics 365 code upgrade the display methods on forms were raising an error. The new rule is that FormDataSource display methods must be static calls. Here is the relevant section from the Docs site:

https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/customize-model-elements-extensions#experiment-with-table-extension-display-and-edit-methods

Our change to display an Employee’s custom Job title looked like this after the upgrade:

[ExtensionOf(formDataSourceStr(HcmWorker, JJEAdditionalEmplTable))]
public final class HCMWorker_DS_JJEAdditionalEmplTable_JADOperation_Extension
{
    static display Description jobTitleDescription(JJEAdditionalEmplTable _additionalEmplTable)
    {
        Description ret = '';
        if (_additionalEmplTable)
        {
            ret = JJEJobTitles::find(_additionalEmplTable.JobTitle).Description;
        }
        
        return ret;
    }
}

In the form designer now you need to refer this display method as a static call as per below in your extension:

HCMWorker_DS_JJEAdditionalEmplTable_JADOperation_Extension::jobTitleDescription
FormDataSource display methods must be static

This should eliminate the error messages for your custom display methods.

DictSecurityKey is deprecated

In the new Microsoft Dynamics 365 Finance and Operations release a lot of things have changed in terms of reflection. One of them that we have used frequently for security access validation is gone, DictSecurityKey is deprecated.

You can find a list of still available classes which are mostly used against AOT objects here:

https://docs.microsoft.com/en-us/dotnet/api/dynamics.ax.application

For example when you wanted to hide a tab on a form in X++, you could just use reflection to do the validation like this:

dictSecurityKey = new DictSecurityKey(buildTabpage.securityKey());
(dictSecurityKey && dictSecurityKey.rights() != AccessType::Delete));

The security framework has been improved/redesigned in D365FO, and now you can achieve the same with the following code:

SecurityRights  securityRights = SecurityRights::construct();
securityRights.formControlAccessRight(form.name(classId2Name(classIdGet(this))), buildTabpage.name()) != AccessRight::Delete;

Incorrect auto upgrade on custom methods

During our upgrade journey from AX 2012 to Microsoft Dynamics 365 Finance and Operations we have noticed some problems. The automated code upgrade tool available on LifeCycle Services for your modelstore did an incorrect auto upgrade on custom methods.

When we did the first builds, the following error message was showing up for various code pieces:

Compile Fatal Error: Table dynamics://Table/CCMTmpQuestions: [(39,5),(39,6)]: Unexpected token '/' specified outside the scope of any class or model element.

After checking the source code we have identified that somehow it has inserted extra lines at the end of some table methods, with a single / sign in them:

incorrect auto upgrade on custom methods

The quickest way to locate all those methods are to use our favorite file manager and search tool, Total Commander.

You can press <ALT>+<F7> and do a file search for *.xml in your \AOSService\PackagesLocalDirectory\[YourPackageName] folder for the following Regular expression value. You must tick the RegEx checkbox:

(^    \/)$

This has revealed all incorrect files, which we could fix in bulk. You can use similar approach as above to quickly find anything in the file-based Dynamics 365 Finance and Operations code repository.

Once you quick-replace these characters with a blank line, you are done fixing the incorrect auto upgrade on custom methods.
