Create scalar variables that you can use to pass information between the steps of an activity. Local variables require less memory and run faster than regular parameters.

For example, you can simplify a highly nested expression by using local variables to break up that expression into component parts. As a result, the expression is easier to read and troubleshoot.

Your application stores local variables together as fields in the Java class that Pega Platform generates to implement the activity. Local variables do not appear on the parameter page.

You can reference a local variable in a Property-Set method by using the Local keyword, as well as in Java steps.
