Item "Use of derivative" and "Unique Transactions Identifier" in Open Derivatives must be reported (S.08.01, EIOPA rule BV1139)

A blocking check on the open derivatives template (S.08.01), in the quarterly solo (QRS), quarterly group (QRG) and quarterly branch (QRB) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

Item "Use of derivative" and "Unique Transactions Identifier" in Open Derivatives (S.08.01) must be reported

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV1139-1 and BV1139-2), and a failure names the one that failed.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark S.08.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

Which returns it applies to

EIOPA applies it to quarterly group (QRG), annual group (ARG), quarterly ECB branch (QEB), quarterly ECB solo (QES), quarterly branch (QRB), quarterly solo (QRS), annual branch (ARB), annual solo (ARS), annual ECB solo (AES) and annual ECB branch (AEB) returns, as a blocking check.

EIOPA's formula, for BV1139-2. Cells are written as {t: table, r: row, c: column}.

if (not(isNull({t: S.08.01.01.01, c: C0240, z: Z0001}))) then not(isNull({t: S.08.01.01.01, c: C0110, z: Z0001})) and not(isNull({t: S.08.01.01.01, c: C0041, z: Z0001})) else true()

BV1139-1:

if (not(isNull({t: S.08.01.04.01, c: C0240, z: Z0001}))) then not(isNull({t: S.08.01.04.01, c: C0110, z: Z0001})) and not(isNull({t: S.08.01.04.01, c: C0041, z: Z0001})) else true()

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
