Represents an Action in the Business Data Connectivity (BDC) service. A type of MetadataObject that represents a URL that triggers the display or manipulation of data related to an Entity or an entity instance. Actions are contained by an entity. Actions contain ActionParameters.
External content types can have actions. You can use BDC actions to build applications with write-back scenarios. For example, you can create a Customer Profile view that enables a user to update profile information directly in an external system such as SAP. Actions are implemented as links, so you can also use actions to perform simple tasks such as to send an e-mail message or open a customer’s home page.
