I have just started with SAP NW Gateway and in a learning stage.
I have some questions on the SAP NW Gateway development aspects.
1. Whether we need to develop the services in the backend (SAP ECC - SEGW transactions) and need to only expose the NW Gateway system or we need to develop the business logic in backend (SAP ECC) and need to develop the interfacing components (NW Gateway - SEGW)?
2. Are there any development guidelines (preferrably published by SAP)?
Anticipating your response.
