Guiding by IMSI, call start time is after service's disconnect date plus grace.
Common Cause
The call start time of this usage record is after the disconnect date of the service.
Common Resolution(s)
Actions you can take to resolve the problem:
Change the disconnect date of the service to be later so this usage will bill to this service.
If end grace doesn’t reach forward far enough, consider changing the end grace setting in Admin Console.
Details
Each service has an effective date and a disconnect date. The call start time of each usage record billed to a service must fall between these dates (actually there is an end grace period setting that extends the end date to be even later by a number of days, so that usage such as this can load). In this case the usage is dated after the disconnect date of the service (including the end grace period).
