A logical system gives a client a unique "name" which can be referenced by other clients within the SAP landscape. Once you have created a logical system, use the SCC4 transaction to assign the logical system to a client.
Normally, you create the logical system before creating a client so that both start out together. Adding a logical system to a client after the client has been in existence and in use to a long time period could cause referencing problems between that client and the rest of the SAP systems.
