Service MaintenanceLocate this document in the navigation structure

Introduction
Use the Service Maintenance function in the Service Builder to register and maintain each service in an SAP NetWeaver Gateway system. This function also enables you to maintain services created and redefined directly in the Service Builder (in an SAP Business Suite backend system) as opposed to navigating to another system such as an SAP NetWeaver Gateway hub system. The Service Maintenance offers the following functions:
  • Register the service in an SAP NetWeaver Gateway system.
  • View all the SAP NetWeaver Gateway systems in which the service is registered.
  • Navigating to Gateway Client from Service Builder
  • View the error log of the service in the registered SAP NetWeaver Gateway systems.
  • View the service document.
  • View the service activation status of the service in the registered SAP NetWeaver Gateway systems.
Prerequisites

The SAP NetWeaver Gateway systems in which you want to register the service must be configured under the following path: Start of the navigation path SPRO Next navigation step SAP NetWeaver Next navigation step Gateway Service Enablement Next navigation step Backend OData Channel Next navigation step Connection Settings to SAP NetWeaver Gateway Next navigation step SAP NetWeaver Gateway Settings.  End of the navigation path.

  1. Log onto the SAP NetWeaver Gateway system.
  2. Open transaction SEGW. The SAP NetWeaver Gateway Service Builder opens.

    Registration Status

    Indicator that represents the registration status of the service in the selected system. The statuses are as follows:

    • Green light indicator

      Service Registered from this system - The service is registered from the current system.

    • Yellow light indicator

      Service with the same name registered from another system - There may be instances when a service with the same name as your service is already registered in the target SAP NetWeaver system. In such instances this status is shown.

    • No indicator

      Service not registered - The service is not yet not registered in this system. You can proceed and register the service in the current system.
