Overdue data is defined as interval meter reading data that is now deemed as missing as it has not been received from the date it was last expected. It also highlights where no data at all has been received.
...
- a periodic channel which is recording data for every interval on a daily basis. If the data is not received for the day before last, then this would be deemed overdue.
- a periodic channel which is recording data for every interval on a monthly basis. If the data is not received for the previous month at the start of the next month, then this would be deemed overdue.

Examples
...
Here, if data had been received up to and including 21/07/2019, the data would be deemed overdue from the 24/07/2019
- Data should be received monthly, and I want to know if I have not received data 5 days after the end of the previous month:
- Data Load Frequency should be set to "Monthly"
- Offset should be set to "4"
Here, if data had been received up to and including 30/06/2019, the data would be deemed overdue from the 05/08/2019.
...
Define the combination of data values that should be considered missing data.
Options include:
- Zero - No Error
- Checks for recorded values of '0' AND a status of 'No Error'. This represents data that the source metering system has sent as an actual meter reading value of zero. This should be used with caution as could represent valid data - it is intended to check meters which never expect to receive readings with a value of zero based on their operation.
...
An on/off toggle to determine whether the system should automatically estimate the data that is deemed to be overdue, based on an average from a historical period (specified below).
...
Specify the number of weeks that should be used as a basis when calculating the data to use for automatically extrapolating historical data.
More information about how this feeds into the system processing that it supports when filling the data can be seen here.
