The System Landscape Directory of SAP NetWeaver (SLD) serves as a central information repository for your system landscape. More information: System Landscape Directory

Bear in mind that the abbreviation SLD is not intended to define a product, since the System Landscape Directory is part of SAP NetWeaver. This abbreviation is only intended to improve readability.
Systems that are installed in your system landscape can periodically send data to the SLD. To do so, you have to configure them.
