Defining End Points 
An end point represents a technical point of access to a system. End points are defined at configuration time to specify the technical call information for the business systems implemented in the system landscape. This information is located in the Integration Directory and is used at runtime to map logical receivers (business systems) to physical addresses during technical routing.
End points are defined for the business systems that receive messages.
Different end point types must be specified depending on whether adapters are implemented on the receiver side for message processing, and if so, which particular adapters.
For a complete description of the technical access to the system, you can also specify logon data when using particular end point types. Logon data is created and edited independently of end points to ensure that collaborative processes are as flexible and reusable as possible during configuration.
Integration
Logical business systems and technical systems in the system landscape are described and managed in the System Landscape Directory. Logical systems are used when configuring a collaborative process in order to map the message flow within the system landscape. Technical systems in turn specify access points (protocol, host, port), with which a system can be accessed.
By separating logical and technical systems you can make changes to the technical settings without altering the configuration of the entire process.
Access information for technical systems (end points) is saved in the Integration Directory. The required information can be imported from the System Landscape Directory at configuration time, provided it is located there. This information is used to automatically identify end points for a receiver system and is used to provide default values when creating end points.
Features
End points are defined as configuration objects at configuration time. The Integration Builder has a variety of tools for creating, editing, and displaying end points. Use these tools to perform the following tasks:
· Display an overview of end points
· Display/change individual end points for a receiver
End points can also be identified automatically from the System Landscape Directory. For more information, see Identifying End Points Automatically.
You can specify one or more end points for a receiver business system.
