Dynamic Field Value Substitution means dynamically substituting the email id of the person
in the role specified in the ‘To Field’ of the email setting.
For example consider the case where email should be triggered to the submitter of the workflow.
To access the ‘Mail Settings’ screen, follow the below link:
‘Control Centre->Workflow->Emails’ icon under the sections/groups.
In this case the word ‘submitter’ will be used between 2 hashes before and after the word. eg: ##submitter## in the ‘To Field’.
The below screen shot shows how this feature is used in the cflow application.
