Distributors can view billing reports in any stage of the billing report cycle, although you can only perform actions on billing reports that are "Under review".
For more information about the information contained within a billing report, see Billing Reports.
For more information about the statuses of billing reports, see Querying Billing Reports.
Note:
When viewing a billing report currently in the "MSP preparing" status, only the fields related to the partner's usage report display values and the values may be subject to change once the partner submits the official usage report.
