About Voiding Billings After Recognizing Revenue
If you void an agreement billing after you have already recognized revenue, you must run the amortization process.
Once you have recognized revenue for an agreement billing, voiding that billing requires that you rerun the amortization process, since the system does not automatically update the Revenue and Deferred Revenue accounts. When you rerun the amortization process, the system backs out the revenue that you recognized for the voided billing from the Revenue account. It then backs out any remaining deferred revenue from the Deferred Rev account.
