7.18 ECVAA-I029: (output) MVRN Acceptance Feedback


Several variants of the ECVAA-I029 MVRN Acceptance Feedback Report are supported. The variant received depends on whether the recipient is the submitting MVRNA or associated Party and what reporting option has been selected (see ECVAA-F004).

All variants of the report have the same basic structure but may contain differing sets of optional fields and require alternative interpretation of particular fields. The contents of the report depend on reporting option selected for each MVRNA or Party for the associated MVRNAA. The reporting options are:14

1. No Feedback; in this case no feedback report is sent to the MVRNA or Party specified for any MVRN submitted under the MVRNAA.

2. Feedback (Acceptance Only); if a potential recipient has specified this option, a feedback report is sent only if the recipient is the submitting MVRNA or associated Party. The report contains details of the submitted MVRN and no matching data.

3. Feedback (Matching); if a potential recipient has specified this option, a feedback report is sent them if they are the submitting MVRNA or associated Party with full details of the submitted MVRN and matching data. They will also receive a feedback report if they are the non-submitting MVRNA or associated Party. In the latter case the report will contain basic details of the latest processed MVRN for the associated counterparty and matching data. The variant is only available after the P98 Implementation Date. The table below details what will be provided to each interested Party or Agent.

The feedback report is only generated if the notification start date is within the next 72 periods. The feedback report will contain all Settlement Periods (i.e. from period 1) in each reported Settlement Day.



The table below lists all fields that could be contained in the report and the expected content for each reporting option (1, 2 or 3 above) where the recipient is the submitter (submitting MVRNA or associated Party) or non-submitter (non- submitting MVRNA or associated Party). ). Note that for a Single Notification, the MVRNA and both Parties are associated with submission and their reports will be generated as shown in the “Submitter” columns in the table below.

* - Note that, in this case, a match report will only be sent to the non-submitter if they have already had a corresponding MVRN processed, and the start date of that MVRN is within the next 72 periods. Any report generated before this point would have contained only the other MVRNA’s latest, unmatched position.

In summary, the 3 possible report variants are:



  • Submitter / No match; the basic Acceptance Feedback Report with no matching.

  • Submitter / Match; full acceptance feedback with matching report.

  • Non-Submitter / Match; essentially just a matching report.

** - Data reported in these fields is as reported to the submitting MVRNA and their associated Party. This gives the non-submitter information on how the position held on behalf of the counter party and consequently the matched position may have changed.

Interface ID:

ECVAA-I029



User:

BSC Party, MVRNA



Title:

Meter Volume Reallocation Notification (MVRN) Acceptance Feedback



BSC reference:

P4, CP725, P98



Mechanism:

Electronic Data File Transfer



Frequency:

Continuous, for accepted MVRNs



Volumes:

Medium


Interface Requirement:

The ECVAA Service shall issue Meter Volume Reallocation Notification Acceptance Feedback to the submitting MVRNA and the associated Party (or Parties) continuously to report the acceptance of MVRNs where settlement period 1 of the effective from date on the MVRN starts within a parameterised 36 hours (72 settlement periods) of receipt of the MVRN.


Where a position has already been received from the non-submitting MVRNA, the ECVAA Service shall also issue Meter Volume Reallocation Notification Acceptance Feedback reports to the non-submitting MVRNA and their associated BSC Party continuously to report the matching of MVRNs where settlement period 1 of the settlement date for which the match occurs starts within a parameterised 36 hours (72 settlement periods) of the match being made.



The Meter Volume Reallocation Notification Acceptance Feedback shall comprise:


Accepted Meter Volume Reallocation Notification:

MVRN ID - Reference Code

Notes:

The acceptance feedback message echoes back the data sent in the MVRN (with the exception of the key) with the following additions or modifications:


Effective From Date: This will contain the Applied From Date. This will be the later of the Effective From Date received in the notification and the Current Date. The Current Date is the earliest Settlement Date for which at least one Settlement Period has not passed Gate Closure at the time the ECVAA receives the notification.
First Effective Period: This will be set to the number of the first settlement period on the Applied From Date of the MVRN for which gate closure had not passed at the time of receipt of the MVRN. The notification has been applied starting with on the reported here.
ECVAA Transaction Number: This value is the transaction number under which the MVRN was loaded. This can be compared to the transaction number provided in the Forward Contract Report to determine if an MVRN is included in the report. The ECVAA shall ensure that Acceptance Feedback Reports generated in response to notifications from a single Agent have sequence numbers which follow the same order as the transaction numbers which they contain.
Where the recipient is the submitter of the MVRN triggering this report, the MVRNA Id and MVRNAA Id are those of the Agent associated with the recipient of the report. Where the recipient is the non-submitter, the MVRNAA Id is always null.
The Matched Reallocation Dates group will be reported for any Settlement Date where Settlement Period 1 of that date starts within a parameterised 36 hours (72 settlement periods) of receipt of the MVRN.
The Matched Reallocations group contains the latest received Metered Volume Reallocation for each Party from their nominated MVRNA and the latest matched Metered Volume Reallocation. Matched data is reported from Settlement Period 1 of the first day covered by the Notification, but only Settlement Periods for which a MVRNA has submitted data will be reported. The sign of matched volume values is consistent with that in the received MVRNs.
The MVRNA or BSC Party will only receive a Meter Volume Reallocation Notification Acceptance Feedback if they have opted to receive them in their Reporting Options (see ECVAA-F004) for the associated MVRNAA. Furthermore, the matched and unmatched groups will be reported only if the recipient has selected matched data in their Reporting Options.
