hi,

1) In visual Admin --> SLD Data Supplier

You specify the connection parameteres with user name & password to connect to the SLD,

give localhost:50000 (if u are using SLD of local WAS)

give <RemoteSLDServer>:<port> (if u r using SLD of some remote server)

2) Now in SLD, you create a technical system, which will be connecting SLD to R/3 system.

3) Now using above technical System, you define & create Logical System (JCo Connections) in your content Administrator of Web Application Server, on which you will deploy your Dynpro Application.

Hence your application will connect to R/3 function modules using JCO's which will use technical system defined in SLD & which will be connected & authorized by configuration Visual Administrator.

Hope you will get clear idea from above.also check out following link
