SIS & RA Break-out Sessions - IATA

ACH Late Submissions Process
Invoices submitted to SIS after 12:00pm EST on closure days and
intended for the period which has just closed will fail validation for incorrect
billing period.
Members therefore have 2 options from the Processing Dashboard
1. Select the failed invoices from the processing dashboard and click the
Mark for Late Submission button.
This will send a request to ACH Operations to accept the invoices for the
closed period.
2. Select the failed invoices from the processing dashboard and click the
Increment Billing Period.
This will automatically push the invoices to the current open period
