You can customize source code and metadata of model elements that are shipped by Microsoft or third-party Microsoft partners. You also have the option to opt-out of these cookies.

Upgrades and deployments are tedious when compared to the extensions approach because here post upgrades the code fixes, and the dependent components/ elements need to be manually fixed, in most of the scenarios. During development, only the extension packages are compiled, and this reduces the time taken to deploy. ISV layer – Approved Microsoft software vendors could modify System layer in the ISV layer. Later, if you want to upgrade to Platform Update 3 or later, the development team needs to move the customizations and adopt the extensions based approach for smoother upgrades.

Code customizations sit on a separate package but the existing model and source code. As an example, let’s look at steps to create overlays for the Application Suite: Extensions are a relatively new technique that extend standard source code or metadata without affecting standard application artifacts. However, overlayering may increase the cost of upgrading the solution to the new version. And change properties at the data-source level, Add new fields in an existing table: Right click on the table >> Select create extension.

On model creation, if you do not choose the package you want to modify using “Select existing package” option you create an extension model and can only change existing objects using the new AX7 extension possibilities. Assemblies (.dlls) that are created for customized packages are same as the base package assemblies (.dlls), and these are protected by the layered approach. (References: https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/migration-upgrade/upgrade-latest-update), Navneeth Nagrajan is a Technology Specialist at Deloitte Australia focussing on design, development, integration, and implementation of the Microsoft Power Platform (primarily PowerBI, Common Data Service and Flow) and Dynamics 365 for Finance and Operations ERP. For example, solution developers can provide code in the SLN layer, independent software vendors can use the ISV layer, and value-added resellers can use the VAR layer. VAR layer – Implementers could modify both the ISV and the System layer in the VAR layer of code. 2. Assemblies (.dlls) that are created from the customized packages are separate from the base package. Extensibility requests 3.
