Logical components describe a function, and group the technical systems that provide this function, in different roles. They are used, for example, by business process planners and software administrators, who are typically not concerned with the technical details of the system implementation.
Logical components are sets of technical systems that need to be synchronized during change processes, for example development, test and production system.
The technical systems building the logical component typically use the same installation number and are linked to each other by transport routes.
A logical component is a high level view of an application, to plan and maintain it.
Business processes refer in their descriptions to logical components.
They form the link between the business perspective and technical perspective of a landscape , and connect the technical systems with the planning landscapes.
To plan the system landscape, a logical component can already be defined without a technical system assignment. In this case, you only assign a product instance.

in the SAP Community Network at https://scn.sap.com/docs/DOC-31897.
Note
As of SAP Solution Manager 7.1 SP09, logical components are managed in a new repository and no longer in transaction SMSY.
Migrate logical components (automatic activity)
The migration includes logical components that were previously created or changed by a user in transaction SMSY.
Migration is only relevant if you are upgrading from a previous version of SAP Solution Manager. For a new installation of SAP Solution Manager 7.1 SP09 or higher, migration is not required.
You can execute the automatic activity Migrate Logical Component Data
in the SAP Solution Manager Configuration
(transaction SOLMAN_SETUP) under Automatic Activities
. Choose the Start Transaction
link.
For more information, see the help text in the Documentation
column.
Display, create, and edit logical components
Choose
.Or start transaction LMDB directly and choose the Logical Components
tab.
For more information, see the documentation in the UI.
Assign a logical component to a technical system
Apart from the logical component editor in the LMDB, you have the following options:
Under Configure System
. Log messages tell you if information is missing or inconsistent. These checks prepare a technical system so that it can be used for Early Watch Alerts, for example.
You can also start transaction LMDB and choose a technical system from the Technical Systems
tab. In the navigation tree, choose Software
and Add Logical Component
. For more information, see the documentation in the UI.
Check to which logical component a technical system is assigned
Start transaction LMDB and choose a system from the Technical Systems
or Product Systems
tab. In the navigation tree, navigate to the Software
information for a technical system, where you find the assigned logical components.
Once the logical component has been created, you can assign it to projects and solutions. You have two options:
Start transaction LMDB, select a logical component on the Logical Components
tab, and choose Edit
. On the Overview
screen, choose .
In the Solution Manager Administration
work center, choose Solutions
. You can navigate from within a project to the managed systems. For more information, see Assigning Logical Components to the Project.
To monitor systems and business processes, for example, you can assign the logical components to a solution.
Start transaction LMDB, select a logical component on the Logical Components
tab, and choose edit. On the Overview screen, choose .
In the Solution Manager Administration
work center, choose Solutions
. You can navigate from within a project to the managed systems. For more information, see Assigning Logical Components to the Project.
