What is logical System in SAP ?

 Logical system enables the system to recognize the target system as an RFC destination. Logical system is required for communication between systems within the landscape. You need a logical system when you create a new client in SAP
T-Code to create Logical System in SAP is BD54
Logical System is transportable.


How to create Logical System in SAP ?

1. Run transaction code BD54. Click on pencil icon to covert from display to change view. Then, click on New Entries.

 
2. Use the following naming convention for the logical system names, <System ID>CLNT<Client>. Save your entries, which are included in a transport request. Create the logical system name for the central system in all child systems.

 

or ex. if your new client no is 500 and SID(System ID) if P10 then logical system will be,

P10CLNT500
