A number of minor changes are required to the market messages arising from errors found in testing.
The changes required are:
Market Message 110
CoS read arrangement is a mandatory field. As this field is optional on message 010 (i.e. only to be
provided for NQH sites) it must also be optional on 110.
Market Message 014R
Optionality of meter point address and customer name segments should be changed from Mandatory to
Optional.
