Create and Edit Technical System Information 
You can create and edit a technical system in Landscape Management Database (LMDB), manually. This can be required if there is no data supplier for a system, or if a firewall avoids the exchange of information.
For some system types, manual changes are required because, for example, information delivered by older data suppliers is no longer sufficient.
Note
Avoid manual creation and editing of system information, it can become inconsistent or obsolete.
Register technical systems automatically with data suppliers, as described under Register Technical Systems Automatically by Data Suppliers.
Data from the System Landscape Directory (SLD) will no longer be updated by automatic synchronization once you changed manually in the LMDB, because the rank of the LMDB is higher than the SLD rank.
Manually created data also must be updated manually.
See Complete Technical System Information Manually.
If this information about the installed product instances of a technical system is not automatically provided by data suppliers, you must define this information manually. Finish the product instance assignment for the technical system before you assign it to a product system. Each subsequent change needs to be carefully propagated to the related product systems that contain the technical system.
Incorrect information that was provided automatically must be corrected in the data supplier. To avoid inconsistencies, manual correction in LMDB must only be considered in emergency.
