Dynamics 365 Finance & Operations Custom Feature Management

📌 Overview

The DAX Custom Feature Management framework provides a structured way to manage custom features in Dynamics 365 Finance & Operations (D365FO).
It allows developers to enable/disable features either globally (cross-company) or per company, ensuring flexibility and control over new customizations.

This solution is designed and maintained by DAXONET GROUP SDN BHD.

✨ Features

• Core model for managing custom features in D365FO.
• Interfaces for cross-company and per-company feature toggling.
• Easy-to-use implementation pattern (singleton instance).
• Integration with forms, menus, and event handlers.
• Support for enabling/disabling customizations dynamically.

---

⚙️ Installation

📌 Note: Installation details will be updated in future versions.

1. Import the model into your D365FO development environment.
2. Synchronize the database.
3. Build the project.

🚀 Implementation

Step 1: Create a Custom Feature Class

Implement one of the provided interfaces:

• DAXCustomIFeature → Feature enabled cross-company.
• DAXCustomIFeatureCompany → Feature enabled per company.

Example:

internal final class MyCustomFeature implements DAXCustomIFeature
{
    private static MyCustomFeature instance;

    private void new() { }

    private static void typeNew()
    {
        instance = new MyCustomFeature();
    }

    public static MyCustomFeature instance()
    {
        return MyCustomFeature::instance;
    }

    [Hookable(false)]
    public str featureNumber() { return 'CR123'; }

    [Hookable(false)]
    public str displayName() { return 'My Custom Feature'; }

    [Hookable(false)]
    public int module()
    {
        return FeatureModuleV0::InventoryAndWarehouseManagement;
    }

    [Hookable(false)]
    public boolean isEnabled()
    {
        return DAXCustomFeatureStateProvider::isFeatureEnabled(
            MyCustomFeature::instance()
        );
    }
}

Step 2: Add Handlers and Extensions

Attach feature toggles in forms, menus, or methods:

[FormEventHandler(formStr(InventLocation), FormEventType::Initialized)]
public static void InventLocation_OnInitialized(xFormRun sender, FormEventArgs e)
{
    boolean isEnabled = MyCustomFeature::instance().isEnabled();
    sender.dataSource('InventLocation').object(fieldNum(InventLocation, MyField)).visible(isEnabled);
}

⚡ Quick Start Example

Here’s a minimal working implementation you can copy-paste to test the framework:

// Feature class
internal final class DemoFeature implements DAXCustomIFeature
{
    private static DemoFeature instance;

    private void new() { }
    private static void typeNew() { instance = new DemoFeature(); }

    public static DemoFeature instance()
    {
        return DemoFeature::instance;
    }

    [Hookable(false)]
    public str featureNumber() { return 'DF001'; }

    [Hookable(false)]
    public str displayName() { return 'Demo Feature Toggle'; }

    [Hookable(false)]
    public int module()
    {
        return FeatureModuleV0::SystemAdministration;
    }

    [Hookable(false)]
    public boolean isEnabled()
    {
        return DAXCustomFeatureStateProvider::isFeatureEnabled(
            DemoFeature::instance()
        );
    }
}

// sample form handler
[FormEventHandler(formStr(SysUserInfo), FormEventType::Initialized)]
public static void SysUserInfo_OnInitialized(xFormRun sender, FormEventArgs e)
{
    boolean enabled = DemoFeature::instance().isEnabled();
    sender.design().controlName('UserGroup').visible(enabled);
}

//Sample for menu handler
[SubscribesTo(classstr(SysMenuNavigationObjectFactory), staticdelegatestr(SysMenuNavigationObjectFactory, checkAddSubMenuDelegate))]
public static void menuItemVisibilityHandler(SysDictMenu _rootMenu, SysDictMenu _subMenu, SysBoxedBoolean _subMenuVisibility)
{
	if (_subMenu.isMenuItem())
	{
		var metaElement = _subMenu.GetMenuItemMetaElement();
		if (metaElement != null)
		{
			if (metaElement.Name == menuItemDisplayStr(DemoSetup))
			{
				_subMenuVisibility.value = DemoFeature::isEnabled();
			}
		}
	}
	else if (_subMenu.isTileReference())
	{
		var metaElement = _subMenu.getTileMetaElement();
		if (metaElement != null)
		{
			if (metaElement.Name == tileStr(DemoWorkspace))
			{
				_subMenuVisibility.value = DemoFeature::isEnabled();
			}
		}
	}
}

👉 Once deployed, navigate to System administration > Setup > Custom feature management and enable Demo Feature Toggle.
You should see the User Group control in SysUserInfo form toggle visibility based on the feature’s status.

🔑 Enabling Features

On development VMs, records are not auto-created.
Run the following URL to update setup:

https://<host>/?cmp=dat&mi=SysClassRunner&cls=DAXCustomFeatureManagementSetup

Navigation in D365FO:

• System administration > Setup > Custom feature management
• System administration > Setup > Custom feature management by company
