The System Landscape Directory of SAP NetWeaver (SLD) serves as a central information repository for your system landscape. A system landscape consists of a number of hardware and software components that depend on each other with regard to installation, software updates, and demands on interfaces.Information in the SLD is used by various SAP tools, for example, for planning and performing upgrades to the system landscape (Software Lifecycle Manager of SAP NetWeaver), finding destination information for ABAP systems and Web services (Web Dynpro), and for maintaining development information by the SAP NetWeaver Development Infrastructure (NWDI).
Features
● The SLD stores information about all installable and installed components of a system landscape. It is based on the standard Common Information Model (CIM). The CIM standard is a general, extensible schema for describing the elements in a system landscape. SAP has enhanced the CIM standard with classes for SAP-specific content.
● SAP provides both a Web-based user interface (UI) for interactive access and client APIs for programmatic access in ABAP and Java.
● SAP provides information about installable SAP software, dependencies and recommended scenarios and regularly publishes updates on SAP Service Marketplace. You can browse this information in the software catalog views. You can also manually add information about third-party components to the SLD.
● SAP software components that are installed on technical systems are registered automatically and on a regular basis in the SLD. Thus the SLD always contains up-to-date information about the installed system landscape. You can view this information in the technical systems views, and can aggregate and group it in the landscapes views.
● In addition, you can use the SLD for name reservation in the NWDI. It contains the master list of all reserved names used in development, such as development component names, Java package names, and database object names.
● The Exchange Infrastructure (XI) uses the SLD to store information about business systems, which are logically connected to technical systems.
