Here's something basic that you might miss when creating Revenue Elements through a Journal Entry.

The Revenue Recognition Rule will be greyed out if the user selects a Deferred Revenue Account instead of an Income Account on the journal entry line.

Take note that the Deferral Account will be selected on the Income Account Set up. Like this one:

After selecting the appropriate Income Account on the journal entry line, the Revenue Recognition Rule field will now be available.

And once the journal entry is saved, the account will then be converted to the associated Deferred Revenue Account.
