Input/Output parameters in orchestrations – Adding Parameters to Orchestrations

You can specify what parameters your orchestration should take in the Orchestration View window. An orchestration can take the following items as parameters:

• Messages
• Variables (including objects)
• Correlation sets
• Role links
• Ports

Parameters can be passed between orchestrations as in parameters or out parameters.

• In parameters can be passed by value or by reference.
• Out parameters can only be passed by reference.

Parameters can include variables, messages, correlation sets, role links, and ports.

To set orchestration parameters

1. In the Orchestration View window, use the Orchestration Parameters folder to add variables, messages, and ports.
2. For each item added to the Orchestration Parameters folder, use the Properties window to specify the Direction property:
   • In – a parameter passed in by value.
   • Ref – a parameter passed in by reference.
   • Out – a parameter passed out by reference.
