When Is Debt Monitored For Write Off Purposes?
The write-off monitor only reviews a service agreement when the following conditions are true:
The service agreement is stopped and reactivated.
If the service agreement is a "billable charge" SA (as identified on its SA type), all of its billable charges must appear on a bill segment AND the bill segment's bill's due date plus grace period must be on or before the business date.
If the service agreement is not a "billable charge" SA AND it is billable (as identified on its SA type), the SA must have a closing bill segment (i.e., it must be final billed) and the bill segment's bill's due date plus grace period must be on or before the business date.
If the service agreement is a sub SA, its master SA must abide by the above conditions.
If the service agreement is not billable, it is possible that adjustments, which affect the SA's debt, exist. The write-off monitor will only review a non-billable SA if all FTs for this SA that have been marked to include on a bill have been swept onto a bill and the bill for any of these FTs has a bill due date plus grace period on or before the business date.
Note: 
Postponing write-off processing. You can prevent the write-off process from processing an eligible service agreement by populating the account's C&C Postpone Date with a future date.
