In any Apama project, you can define a variable that you can use in all your Apama projects. You might find it useful to define a variable in a situation where multiple users share the same project. If the project is dependent on one or more external files, not all users might have the external file stored in the same location. Each user defines a variable to specify the location of a shared file dependency.

You define an Apama project variable in the Apama preferences. For more information, see the description of the Apama preference page Apama Build Path Variables.
