Super Customer Invoicing Issues

1. Supercustomer invoices have been received which have missing days worth of data.
For example invoice received for period for period 28/12/23 to 25/1/24 but missing
data for 18/01/24. This causes invoice validation to fail and manual intervention is
required to reconcile data. No proactive notification was received to alert us to the
issue.
2. Billing periods are not aligned across networks. This causes additional work in
forecasting and preparing accruals. The table  with the issues form lists the billing dates and
billing periods for each DNO.
