    A client is a logical division of data within an SAP system. Some things, like application data are mostly client-dependent, meaning that for example, a G/L account defined in client 123 of system ABC is only visible in that client. Therefore if you logon to client 456 of system ABC you will not be seeing the same database entity (if it is defined at all).

    At a technical level, client dependent data simply resides in database tables that have the client number as a key field (typically the first key field).

    Multiple clients within an SAP system are often used in development, testing and training systems - so that individuals can work in the same system (on the same codeset) but in isolation of each other.

    Very rarely will a production system have multiples clients (ignoring the internal SAP clients like 000 and 066).

    I'd like to add a little more to Scott's description.

    A client a logical division having its own data structure. Usually clients '000' and '006' are installed by default and client '100' is used for customizing.

      I think you mean clients 000 and 066.

      Client 000 was originally an SAP reference client that was never changed by the customer. Typically only administrators have access to client 000 and certain system functions can only be performed in that client (I believe that is the case with applying hot packages).

      Client 066 is for SAP's EarlyWatch service where SAP staff remotely investigate the health of a system. They use this client for tighter security - for example, so that production data is not accessible by their staff.

      As for client 100 being customising, well that is really at the whim of each implementation. I think my favourite is 210, for no particular reason :-).
