Optimize Landscape Data to Enable Landscape Management of Your IT LandscapeTo 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 the systems: 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, where it's edited into a landscape description and used to monitor systems, plan maintenance, updates and upgrades, etc.
A 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 applications you need to maintain your landscape description, gathering and enhancing available 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 Landscapeexplaining terminology, landscape model, best practices, and guiding principles.

Describing Your Installed IT Landscape for Maintenance and Monitoring
- Understanding Landscape Descriptions - Part I: the Simple Approach to Explaining Products, Product Instances, and Software ComponentsIn this blog I try to explain the main entities of SAP's products comparing them with a car and its parts.
- Understanding Landscape Descriptions - Part II: Products and Product Instances in Detail
Products and Product Instances are used to describe software that SAP delivers. It's also these entities that you need to understand to maintain your systems. Read about these entities in some detail including reuse, versioning, and nesting.
- Understanding Landscape Descriptions – Part III: Maintaining Products and Product Instances in SAP Solution Manager 7.1
Products and Product Instances are used to describe software that SAP delivers. Maintenance processes and monitoring work on these entities, because they are installed on the hardware, creating technical systems. Therefore, you have to make sure they are listed correctly in your landscape description. Here are the tools and steps you need to know.
- Products, Product Systems, Product Instances, Technical Systems, and Landscape Patterns in the SAP Solution Manager
Once you come to the installation of products in your landscape you need to take Technical Systems into account, how they are used by products, and how they are grouped.
Best Practices and Trouble Shooting
- Data Adjustment in SMSY after a Upgrade of an SAP NetWeaver Hub System
In this blog, a real life example of a specific type of upgrade and the manual action it requires is explained.
- Information on SAP Solution Manager is available at the Wiki SAP Solution Manager Setup & Configuration.
- Maintenance of System Tracks: To update a single product system, the Maintenance Optimizer provides all the files and the stack configuration file, which can be handed over to the installation tool to apply the files. However, usually, you are dealing with a system track consisting of individual systems for development, quality assurance, production etc. For more information see Maintenance of system tracks with Maintenance Optimizer or Maintenance Planning Guide.
- New: Special Cases in Installation and Upgrade describes different installation options comparing reuse to independend installation of product versions in general, describes the resulting landscape pattern and afterwards discusses specific products.
Centralized Landscape Data Management with SAP Solution Manager
Creating and Managing Landscape Data
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 SMSY, Landscape Verification Tool and monitoring applications.
A complete view of technical systems' data you'll only get with SLD plus LMDB - see http://scn.sap.com/community/it-management/blog/2015/07/10/technical-system-data-delivered-by-sld-data-supplier-and-agents.
Checking Landscape Data for the Maintenance Process
- 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.

Calculation Maintenance Processes in the Maintenance Optimizer
Maintenance Optimizer (MOpz) in 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, centrally accessible from inside SAP Solution Manager.
- In Maintenance Optimizer at the SAP Service Marketplace (login required) you'll find the describing steps and tools in the maintenance process for various releases of SAP Solution Manager:

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.
