System, Application Server and Client ?

Would anyone please tell me what SAP system, Application Server and Client are? I am very much confused with this system number and client number stuff.

Thanks in advance.

    The SAP System is your central instance (3 letter/number designation)

    Application Server is well from my understanding it's a central instance without the database that is hooked to the database in the central instance. Then again you might be referring the the SAP WEB AS (6.10/6.20/6.30/6.40) system which are the WEB Application Servers.

    Each system has a "client" basically a login area on the system containing users and data.

    By default the systems come with "000" which is for system updates and patches and things and "066" which is for "EarlyWatch Alert", not sure if there are other default ones or not.

    Also when you create a new system it has a System number.

    For example I install a new system for SSM 3.1 (Solution Manager)

    System ID/Name (SID): SOL

    System Number: 01

    Then when I want to login I can login to client "000", "066", or "001" which in this case was created during the install of the SSM 3.1.

    Hopefully someone on here will be able to give you more precise info 😊

    Have a look at the documentation at:

    That is a comprehensive description about the Architecture of the SAP Web Application Server.
