MP089 Changes to Appendix R ’Common Testing Scenarios Document'

Proposer Mari Toda
Lead Analyst SEC Change
Date raised 14/10/2019
Implementation date 20 Janaury 2020 (Ad-hoc SEC Release)
Latest update This modification was implemented in an ad-hoc Release on 20 January 2020.

What is the issue?

Additional User Roles have been added to three Service Reference Variants (SRV) through SEC modifications that are to be implemented in the November 2019 SEC Release. These additional User Roles for the three SRVs have not been mandated Appendix R' Common Test Scenario Document' (CTSD), and therefore the additional users are not required to perform testing during the User Entry Process Testing (UEPT) or Additive UEPT. This means that the additional users may not perform testing on these SRVs following the November 2019 SEC Release.

There has also been a contradiction identified in the CTSD where it requires the Electricity Distributors (ED) User Role to test an SRV against a SMETS1 Device. However, this SRV is not available to SMETS1 Devices, as defined in Appendix AD 'DCC User Interface Specification'.
