To put it simple, IT landscapes are made of hardware boxes and the software that runs on this hardware. This might, in the simplest case just one computer running a set of programs, working independently of each other, so you can add and remove programs pretty easily. 
When it comes to business landscapes, this is not what you find: Typically, you have many servers, running a lot of systems with many applications. Some of these programs are so big that they run distributed over many hardware boxes or "systems". More than this, applications connected with each other to allow handling all steps of business processes.
Having tight connections between systems is a huge advantage, but it introduces a coupling between them: So if in need of a new version of a system, you do not delete the old one, but go through an upgrade process, which also has to take compatibility with other systems into account.
And this is, at the end of the day, why you need a correct landscape description: You need to know, what kind of systems you have, what their state is, and what software versions are available, to be able to connect them, monitor them, and manage their maintenance successfully, as shown in this "big picture":

Systems' data is gathered in the SLD and handed over to the SAP Solution Manager LMDB; here it's enriched by agents data and manual added information and used to monitor and run systems. To plan maintenance, updates and upgrades, etc., data is uploaded to the SAP Support Portal Customer Profile, which is read, verified, and enriched with dependency data in the Maintenance Planner.

Landscape Description is like a map - the better it is, the better it will guide you on your journey, so any effort you invest here, is well spent... 
This page is on repositories you need to maintain your landscape description, gathering and enhancing available information.
  • System Landscape Directory (SLD), as a target for technical systems's data suppliers, serving several client applications including the LMDB
  • Landscape Management Database (LMDB), the landscape repository of, feeding into different consumers, including the customer Profile  
  • Customer Profile in the SAP Support Portal, providing the Maintenance Planner with landscape information
The structure lists the tools needed to data handle landscape data the sequence of their appearance (though in the end as you can see it's a circle when repeated updates of landscape data is taken into account).White Paper: SAP Solution Landscape explaining terminology, landscape model, best practices, and guiding principles.

Gathering Systems' Data in the IT Landscape

The System Landscape Directory is where system data is gathered. To get an overview, just follow the link. To read about its functions in detail and see system demos, open the More on System Landscape Directory. Getting technical systems data right in the beginning is crucial for ALM processes, so have a look at the SLD pages, especially, when it comes to topology planning for the SLD.

Landscape Model in SAP Solution Manager

Describing Your Installed IT Landscape for Maintenance and Monitoring

The SAP Solution Manager is central for the management of system landscapes. In detail information on the SAP Solution Manager can be found on the SAP Service Marketplace following the quick link "solutionmanager" (SMP login required). Here information on the landscape description is gathered.In the following you'll find a selection of blogs that shall help you better handle you landscape data, which are a prerequisite for running business applications, systems, and ALM processes alike.

Centralized Landscape Data Management with SAP Solution Manager


The main landscape data tools are SLD (see above) gathering technical systems' data, LMDB hosting and verifying them in SAP Solution Manager, and consuming MOpz and monitoring. Finding landscape data is described in How-to get an Overview of Your IT-Landscape?

Creating and Managing Landscape Data

Landscape Management Database (LMDB)

As of SAP Solution Manager 7.1 the Landscape Management Database (LMDB) offers central access to landscape data for users. It gathers Technical System's information from the SLD as a basis for the landscape description and provides this data to transaction SMSYLandscape Verification Tool and monitoring applications.

Checking Landscape Data for the Maintenance Process

Landscape Verification  Apart from automated processes in handling landscape data, manual steps are required. To minimize errors in landscape data, landscape verification is offered in the SAP Solution Manager for optional use. Follow the link above to read more about this function.
  • Landscape Verification tool can be installed as an Add-On on SAP Solution Manager 7.0 (SP18+)
  • With SAP Solution Manager 7.1, the Landscape Verification tool is directly integrated, with no additional installation required. The functions are as described for SP1 of landscape verification 1.0 for SAP Solution Manager.

Providing Landscape Data in the Customer Profile

Maintenance Planner

Maintenance Planner, a cloud based service of SAP Solution Manager is the central point of access for all maintenance activities. It supports the installation of updates and upgrades and completely manages the maintenance activities for your whole solution, including system conversion to SAP S/4HANA.

The Maintenance Planner is hosted on the SAP Support Portal, offering visualization of the customer landscape, planning of changes and analysis of the impact in the landscape based on landscape data available in the customer profile. A maintenance transaction created to define the scope and target of planned changes can be consumed by SUM and SWPM.
Landscape information used by teh Maintenance Planner is stored in the Customer Profile - see Topology of SLD, LMDB, and Customer Profile – How to Get Reliable Landscape Data in SAP Support Portal as a Basis for Planning.

Planning and Implementing Changes Based on the Landscape Description

The landscape description is the basis for almost all changes of your landscape - even in most new installations, you will take existing systems into account. The tools consuming the landscape data and related sources of information are now described on a dedicated page.
