SAP NetWeaver Gateway: Capabilities and Key Benefits

  • SAP NetWeaver Gateway is a technology that provides a simple way to connect devices, environments, and platforms to SAP software based on market standards.
  • Non-disruptive, any SAP business suite.
  • Easy to develop simple APIs and does not require any tool knowledge.
  • Based on REST, ATOM/OData. The connectivity to SAP applications using any programming language or model is allowed, without the need for SAP knowledge, by leveraging REST services and OData/ATOM protocols.

Gateway Installation / Deployment Options

The deployment options available to deploy SAP NetWeaver are as follows:

Central Hub Deployment of SAP NetWeaver Gateway

  • Gateway server functionalities are used on one dedicated server, the hub system. Against the first option, service deployment takes place on the Hub system.
  • This option is used if either no development must be performed on the back-end system or in case of releases prior to 7.40. or if it is not allowed to deploy the Add-On IW_BEP in the back-end. In this case, the developer is limited to the interfaces that are accessible via RFC in the back-end.
  • Development takes place in Gateway hub system and Business suite back-end systems are not touched. IW_BEP or SAP_GWFND runs in Gateway hub system and nothing is touched in SAP Business suite.


  • Advantages


  • There is no direct access to metadata (DDIC) and business data. Therefore, the reuse of data is limited.
  • GENIL objects cannot be used remotely.
  • In this configuration, access is limited to remote enabled interfaces, like RFC modules, BAPIs, etc.

Embedded Deployment

  • In this , Development takes place in SAP Business suite back-end system. The Gateway system is also installed in the same system.
  • Services are registered as well as published in the SAP Business Suite back-end system.
  • IW_BEP or SAP_GWFND runs in the same system in which SAP Business suite is installed.

Advantages :

It requires less run time as one remote call is reduced.

Disadvantages :

  • For the additional back-end systems, this is not used as a hub.
  • In case of multiple SAP Business Suite systems, the Gateway has to be configured multiple times.
  • This configuration is recommended only for sandbox purposes.
