Technical Communication at Design Time 
The System Landscape Directory (SLD) contains information about the technical communication of the involved systems at design time. In the ES Repository use the system properties com.sap.aii.connect.cr.name and com.sap.aii.connect.cr.httpport to connect to the SLD.
The Enterprise Services Repository is the central store for SAP NetWeaver design objects for service development and their related metadata. The Enterprise Services Repository is an AS Java application and is available to you, if you have SAP NetWeaver Process Integration or SAP NetWeaver Composition Environment in your system landscape.

Each AS Java has a local Services Registry. If there are multiple AS Javas in your system landscape, select one registry to be the central registry. Here you can publish Web services of the system landscape.
To configure the Services Registry, there must be a connection to the UDDI server and to the classification service.
