In Dynamics 365 for Finance and Operations, development requirements can be better achieved using an extension approach on standard application objects. Unlike overlayering in AX 2012, extensions in Dynamics 365 for Finance and Operations don't overlay the base model elements. Instead, it compiles them in separate assemblies, which allows us to customize on standard objects and associated business logic using Event Handler. Extensions provide minimal overhead when a base package is upgraded.
In this recipe, we will be extending InventJournalTrans and adding new fields in it.
