Background documentationA. Describing the System Landscape

 

Correct and up-to-date system landscape information is the basis to plan and to carry out landscape changes like updates, upgrades, and new installations. Landscape data is collected in different ways:

  1. SAP Solution Manager collect system landscape information in the landscape management database (LMDB). For more information, see Managing System Landscape Information.

    With data suppliers, technical systems send information to a central system landscape directory (SLD).

    The SLD synchronizes all information with the LMDB.

    For more information, see Registering Technical Systems Automatically by Data Suppliers and Connecting LMDB to System Landscape Directory (SLD).

  2. Some data suppliers reside outside of the technical systems, such as SMD agents (Outside Discovery). They write landscape data directly into the LMDB. For more information, see http://wiki.scn.sap.com/wiki/x/n4efFgInformation published on SAP site and http://wiki.scn.sap.com/wiki/x/4I-uDQInformation published on SAP site.

  3. You can enrich the automatically provided information in the LMDB by manual entries, for example, about business partner assignments, lifecycle status and other attributes. For more information, see Editing Technical System Information.

  4. The LMDB synchronizes system information with SAP Support Portal, where it is needed for service connections and to calculate updates and upgrades, for example. For more information, see Synchronizing with SAP Support Portal

The following graphics illustrates the flow of system information from the customer landscape to the system landscape directory (SLD), to the landscape management database (LMDB) in SAP Solution Manager, and to SAP Support Portal. The maintenance planner calculates updates, upgrades and new installations, based on this information, and tools from the SL Toolset can install the software in the systems.
