    You can find two Sap router files in SAp - one in the Server in the
    Run Folder - second one while instaling the GUI. SAP Router or
    saproutr files actually helps the Sap to connect to another Sap system
    which in turn is connected to Routing Table.To be more clear SAPRouter
    files connects SAP with Router.

    To configure SAP Router you need use SAP String's explained below in
    my mail as attached.

    A route string describes the stations of a connection required between
    two hosts. A route string has the syntax

    (/H/host/S/service/W/pass)*

    It consists of any number of substrings in the form /H/host/S/service/W/pass .
    H, S, and W must be uppercase!
    Structure
    A route string contains a substring for each SAProuter and for the
    target server.
    Each substring contains the information required by SAProuter to set
    up a connection in the route: the host name, the port name, and the
    password, if one was given.
    Syntax for substrings:
    · /H / indicates the host name-{}-
    Note that the host name must be at least two characters long.

    · /S/ is used for specifying the service (port); it is an
    optional entry, the default value is 3299

    · /W/ indicates the password for the connection between the
    predecessor and successor on the route and is also optional (default
    is "", no password)
