Agreed FINT Replacement Reads Incorrectly Triggering Rolling AQ Calculation

Summary

This change is to prevent a read with a ‘Customer Read Reason’ of ‘FINT’ from triggering an AQ calculation where the estimated transfer read has been replaced.

A change is required to UK Link to ensure when an estimated transfer read is replaced by the incumbent Shipper, the replaced final read does not trigger an attempt to calculate a new Rolling AQ.

When a Change of Shipper estimated read is required, two reads with the same value are created in UKLink. The reads are recorded with the ‘Customer Read Reason’ as ‘OPNT’ as the opening read and ‘FINT’ as the final read.

When an estimated transfer read is replaced the ‘Customer Read Reason’ is updated to ‘R’ (replacement) for the opening read and ‘FINT’ is maintained for the final read.

This change is to prevent a read with a ‘Customer Read Reason’ of ‘FINT’ from triggering an AQ calculation where the estimated transfer read has been replaced.
