Language-independent service interfaces in the ES Repository enable you to define the type of communication and the data to be exchanged for a particular communication party. For example, service interfaces can be used for cross-system communication using the Integration Server or the Web service runtime.
More information: Introduction to Service Development .
You must assign service interfaces in the ES Builder to a software component version. This can be either a local software component version (for content that is not shipment-relevant), or a software component version from the System Landscape Directory. At least one repository namespace must be defined in the software component version.
