Execute Functions
In Dynamics 365 CRM, functions are a way to add server side operations that are not easily defined as CRUD operations such as create, retrieve, update and delete on entities.
Functions can return data. Functions are useful for returning information that does not correspond directly to an entity or collection.
A function can target a single entity or a collection. In OData terminology, this is the binding. You can also have unbound functions, which are referred to as static operations on the service.
Use this action to execute the functions as analysed from Dynamics 365 CRM metadata.
