Change Technical System Information 
For some system types, manual changes are required because, for example, information delivered by older data suppliers is no longer sufficient.
Note
When you create technical system information in Landscape Management Database (LMDB), manually, it will be neither overwritten nor updated by synchronization with System Landscape Directory (SLD) because the LMDB rank is higher than the SLD rank. For more information, see Connect LMDB to System Landscape Directory (SLD).
So, if updates are required for manually created data, you must update the information manually, again..
See Complete Technical System Information Manually.
You must change the installed product instances of a technical system if this information is not automatically supplied. Finish the product instance assignment for the technical system before you assign it to a product system. Any subsequent change needs to be carefully propagated to the product system(s) containing 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.
To change or create technical system descriptions, proceed as follows:
Start SAP Solution Manager: Work Centers (transaction SOLMAN_WORKCENTER) and choose .
(Alternatively, you can access the LMDB directly with transaction LMDB.)
To change existing system information, select a system and choose . Make the changes and save.
To create information for a new system, choose Create System and follow the guided activity.
