Some doubts from SAP OData
I have few question related to SAP OData service and Gateway Hub.
1. Related to Subscription and Notification.
When we enable the Subscription check box while creating the service in SEGW, system automatically creates 2 Entity Sets.
I understood the SubscriptionCollection, but what is the use of NotificationCollection.
2. My understanding is that there should a program like /IWBEP/R_MGW_PUSH_TEST to send the push notification. The question is whether the system takes care of sending Notification to the client automatically without writing the push program ?
3. Subscriptions being saved in a Table /IWBEP/D_MGW_SUB. Now the question is where the notification should save if we have 2 systems/boxes like ERP and NGW Hub.
4. What is the role of bgRFC in the notification process ?
Please share your thoughts.
