You use a correlation to assign messages that belong together to the same process instance.

A correlation joins messages that have the same value for one or more XML elements.

A correlation is therefore a loose coupling of messages: at design time, it enables you to define which message a receive step must wait for, without knowing the message ID.

Landscape:

The SAP System Landscape Directory (SLD) is the central information provider in a system landscape.

The SLD contains two types of information:

Component Information: This is information about all available SAP products and components, including their versions. If there are any third-party products in the system landscape, they are also registered here.

At design time of the integration objects, the component information is extracted from the SLD to define integration scenarios.

Landscape Description: This contains all installed systems in a system landscape.

When a collaborative business process is configured, the landscape descriptions are needed to determine the system information of the business partners involved.

I would suggest you to first search though the forum or SDN (use the search option) before you post queries since most of the basic questions have already been answered multiple times and I am sure you will get many good replies and threads already replied and closed.

One example is this https://forums.sdn.sap.com/click.jspa?searchID=25859234&messageID=5179244

So hope you can help yourself when it comes to basic questions.

Still if you were not able to find help, do post your questions for help.

thanks,

Shabz
