What is a functional change?
A functional change in a Microsoft Dynamics NAV or Microsoft Dynamics 365 Business Central implementation involves using an application functionality not used before, or to change the way certain application functionalities were used in the past.
Note
From the introduction of Microsoft Dynamics NAV 2016 to Microsoft Dynamics 365 Business Central, the development model has changed. As already said, it is not recommended to change the standard of the product as done previously with the old versions of Microsoft Dynamics NAV (in Microsoft Dynamics 365 Business Central SaaS it is not possible to change the standard code). It is mandatory to use the extension model supported by the events for development; in this way, it is possible to preserve the standard product's code and easily remove the customizations installed in the system.
Here are some examples of some new functionalities that a company might want to explore after these ERP systems are implemented.
