We have a requirement where we need to consume an external REST service using Netweaver Gateway. Whenever a Sales Order gets created in ECC we need to call a REST service which will hit some other server. And this service should go through Netweaver Gateway.
As far I have used Gateway whenever an event happens outside of SAP and consumed OData service generated in Gateway. Here I need a reverse operation. I have seen Subscription and Notification concept, but in our case the external server doesn't has a capability to read the notifications.
Please help me to get a solution.
