In general, derived fields available to a process are listed in the Derived Fields folder. Derived fields are available only for the process in which they were created. If you have not created any derived fields in a process, no
Derived Fields folder appears in the list.
To use a derived field in another non-subsequent process, store the derived field expression in the Stored Derived Fields list. Inclusion in the Stored Derived Fields list makes a derived field available for all processes and all flowcharts.
