CP0909 – Deemed Reads where Initial Reads invalid or unattainable

Formal title: Deemed Reads where Initial Reads invalid or unattainable

Summary

SIR2832. Whilst there are defined procedures for deeming reads where valid Final Reads are unobtainable, there is currently no equivalent process for the situation where valid Initial Reads are unobtainable. A number of instances of missing or invalid Initial Reads have been reported and this has been noted as an operational issue. An agreed principle was that “where data is missing or incorrect and processes cannot be operated without this data, estimates can be utilised, preferably using a deemed reading process”.
