Why do transactions require manual scheduling?

If a transaction has a deferred revenue scheduling rule, then all revenue is assigned to the unearned revenue account. You recognize revenue manually for these transactions at the appropriate time, according to the revenue policy of your enterprise.

For transactions assigned time-based revenue contingencies, you can recognize revenue manually if the contingency is met in advance of the specified time period, for example, a customer provides early acceptance of the terms of a post-billing customer acceptance clause.

It may also happen that Receivables can't automatically record certain contingencies, such as the completion of a particular service. In these cases you need to manually schedule revenue recognition.

Note: Once you manually adjust revenue, Receivables discontinues the automatic monitoring of contingencies on the related transactions.
