To create a new derived field from an existing one
1.
From the configuration window of a process that supports derived fields, click Derived Fields.
The Create Derived Field window appears.
2.
From the Field Name drop-down list, select the existing derived field from which you want to create a new one.
The expression for the selected derived field appears in the Expression area.
3.
Change the name of the existing derived field to the name you want for the new derived field.
*
You cannot use the words "Yes" or "No" as names for derived fields; doing so results in database disconnects when these derived fields are called.
4.
Edit the derived field expression as required.
5.
Click OK to save the new derived field and return to the process configuration dialog.
