About this Blog:
Currently a lot of customers use their SAP Gateway system in On-Premise mode to expose OData services and host Fiori like applications.
The OData services which are available in their respective Business Suite system are registered on the SAP Gateway system which acts as a hub.
Below is a simple system landscape which is common in recent days.
AS – IS System:
Targeted user for this blog:

- Gateway developer.
- SAP UI5 Developers.
The Problem statement:
- Investment on the infra for the gateway server.
- Maintenance and upgrade of the gateway software and its associated libraries.
- Maintenance of security system like DMZ setup.
- With more IOT devices getting connected and the need of cloud based system is imperative.
Solution (TO – BE System):
- In order to strengthen and harmonize the cloud-based integration solutions for 'SAP HANA Cloud Integration' and 'Gateway as a Service' we plan to bring these two offerings closer together.
- 'Gateway as a Service' is now called 'HCP OData Provisioning'.
- Don’t need an infrastructure on your On-premise to host the gateway related components.
- Easily integrate your backend services with other Cloud based services like Fiori Cloud Edition, API Management etc.
- Enhanced security mechanism
Pre- Requisites for develop the sample application development:
- SAP Cloud Connector basics.
- SAP Hana and SAP Hana Cloud Integration Trial
account. - WebIDE basics.
Topics to Cover:
- Hana Cloud Connector configuration.
- Getting started with WebIDE.
- HCP configuration to connect ECC
- Sample Application development and deployment in HCP
- Configuration of Fiori FLP on cloud

The Cloud connector runs as on-premise agent in a secured network and acts as a reverse invoke proxy between the on-premise network and
SAP HANA Cloud Platform
HCC acts as the bridge between the On-premise systems and the HANA Cloud Platform.
It combines an easy setup with a clear configuration of the
systems that are exposed to SAP HANA Cloud Platform.
2.Create the virtual system for the business suite system in HCC:
To avoid direct access of the business suite system from cloud, we need to create the virtual system in HCC- access control.
The port should be same for internal and virtual host. All the resource and sub paths of the business suite system Needs to be added.
Note: To Find the Port, execute the sicf TCode in your business suite system àenter the service name as IWBEP and test it A pop-up
window will be displayed, make a note of the host and port name from it.
