Invoice not posting during the scheduled create accounting job

I have an invoice that is in the current open period that is validated but the scheduled job for create accounting is not posting the invoice. When I go the the invoice and post it manually it posted with no issue. Why would the scheduled job not have posted the invoice. The invoice was keyed and validated on 6/26 with and invoice date and accounting date of 7/1. We are on a 4-5-4 calendar so 7/1 is in the current open period and the create accounting job ran successfully with no errors.
