What is Model in D365 F&O

In Microsoft Dynamics 365 Finance and Operations (D365 F&O), a model is a container that holds a set of related application elements, such as tables, forms, classes, reports, and data entities.

A model acts as a logical boundary that separates different application components and allows them to be developed, tested, and deployed independently. It enables developers to organize and manage their customizations and extensions in a modular and structured way.

D365 F&O provides several standard models that contain the application elements required to support standard business processes. These models are referred to as the "base" models, and they cannot be modified.

Developers can create their own custom models to store their customizations and extensions. They can also import or export models to move application elements between development, test, and production environments.

Models can also be used to control access to application elements. By assigning security privileges to models, developers can restrict access to specific sets of application elements based on user roles or responsibilities. This helps to improve security and reduce the risk of unauthorized access to sensitive data.

What is Model in D365 F&O

In Microsoft Dynamics 365 Finance and Operations (D365 F&O), a layer is a logical container that separates application elements into different tiers based on their level of customization and functionality.

There are four standard layers in D365 F&O:

1. Microsoft: This layer contains the standard application elements that are delivered by Microsoft and cannot be modified.

2. ISV (Independent Software Vendor): This layer contains the application elements that are developed by independent software vendors and delivered as add-ons or extensions to the standard D365 F&O application.

3. VAR (Value Added Reseller): This layer contains the application elements that are developed by value-added resellers who customize D365 F&O to meet the specific needs of their customers.

4. Custom: This layer contains the application elements that are developed by customers or partners to customize or extend the functionality of D365 F&O.

Each layer has its own set of application elements, and the layers are arranged in a hierarchical structure. Application elements in higher layers can override or modify elements in lower layers. This enables developers to customize or extend the functionality of D365 F&O without affecting the standard application elements delivered by Microsoft or other third-party vendors.

Layers also play an important role in managing and maintaining the application code. For example, developers can use layers to isolate their customizations and extensions from the standard application code, which makes it easier to manage and update the application over time. Additionally, layers can be used to manage version control and ensure that application elements are deployed in a controlled and organized way.
