CP0645 – Incorrect Default Rules for missing DA Data in SSL300

Formal title: Incorrect Default Rules for missing DA Data in SSL300

Summary

When SIR R2717 was implemented and the defaulting rules for missing Data Aggregator files for Initial Settlement were amended in SL300) incorrect text was included in section 1. 7. 6. 1 for defaulting arrangements. These defaulting rules are valid for NHHDAs only. Defaulting rules for HHDAs are different and should be:
“Missing Half Hour Data Aggregator data – for Weekday, Saturday and Sunday Day Types substitute data from the previous Settlement Day of the same Day Type and for all other Day Types substitute data from the previous Sunday Day Type Settlement Day, with sufficient number of Settlement Periods in respect of each Supplier / Data Aggregator combinations. “
