The syntax is @<variable>@. See How to use replacement variables for more details.
Variable names are case-sensitive!
Action help and document lists variables set by specific actions.
Variable replacements are different than substitution variables. Don't confuse them or their unique syntax.
Last created means the variable is set from the last create or add action.
Referenced means the variable is set from one of the runFrom or get actions.
Within a run script, the getReplacementVariableList action will list currently defined variables except for pre-defined variables (server, runDate).
Within a run script, the setReplacementVariableList action can be used to set custom variables.
Some actions support a reference parameter that provides an opportunity to set a custom variable based on specific information from running the action.
Variables are available within the scope of run action that contains the action that sets the variable or a parent run action. Sibling (runFromList scripts) variable sets are independent of each other.
