Background
During acode review undertaken by the Market Operator (MOSL) in 2020, it was
identified that for some Data Transactions there is a misalignment between the
described behaviour in the codes and functionality in the Central Market Operating
System(CMOS). The misalignments have existed since market opening.MOSL logged
the inconsistencies that it had identifiedand has submitted this housekeeping Change
Proposal to seek to address them.
The issue
CSD 0301(Data Catalogue) – T121.W
CSD0301 does not mandate that the Trade Effluent Tariff Band is included in the T121.W
(Submit DPID)Transaction where the Trade Effluent tariff is banded. However, CMOS
hasa validation rule which mandates inclusion where the tariff is banded. Thisis
required to facilitate the accurate calculation of Primary Charges. The final
recommendation report states that if this data is not included,CMOS will ‘skip’ the
Supply Point during settlement calculations.
CSD 0301(Data Catalogue) – T105.M
