What is event provider in SAP BC-ESI - Enterprise Service Infrastructure?

SAP Term: event provider

• Component: BC-ESI

• Component Name: Enterprise Service Infrastructure

• Description: A special type of consumer proxy which supports different programming models. Depending on the application context, an event is raised by the event provider and sent asynchronously as a normal SOAP message to all event consumers subscribed. Unlike classical Web service communication, an event consumer is highly interested in receiving events. From the perspective of the event provider, it does not matter how many event consumers are subscribed to a specific event. The subscriptions of the event consumers are defined using a list of logical ports. An event is sent to all subscribers, and the application is unable to change the subscription list at runtime. The event provider is generated from the ESR/MDR event interface.

• Key Concepts: 
  An event provider is a component of the SAP Enterprise Service Infrastructure (BC-ESI) that is responsible for providing events to other components. Events are messages that are sent from one component to another, and they can be used to trigger certain actions or processes. Event providers are responsible for creating, sending, and receiving events. 
  
  How to use it: 
  Event providers can be used to trigger certain processes or actions in other components. For example, an event provider can be used to trigger a workflow process in another component. The event provider will send an event message to the other component, which will then trigger the workflow process. 
  
  Tips & Tricks: 
  When using event providers, it is important to ensure that the events are sent securely and reliably. This can be done by using secure protocols such as HTTPS or TLS. Additionally, it is important to ensure that the events are sent in a timely manner so that the other components can respond quickly.
