Open derivatives: the format of a code or text (S.08.01, EIOPA rule BV1243)

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

The item "Counterparty group code and type of code" (S.08.01.01.02 C0340) does not follow LEI ("^LEI/[A-Z0-9]{18}[0-9]{2}$"), "^SC/.*" pattern, or "^None$" in case of natural persons

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the code or text in your return with the format the rule sets out, character by character, including any prefix and any spaces.
  3. 03This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Which returns it applies to

Line4 Check runs it on quarterly solo (QRS), quarterly group (QRG) and quarterly branch (QRB) returns on EIOPA taxonomy 2.10.0. EIOPA applies it to quarterly ECB branch (QEB), quarterly ECB solo (QES), quarterly branch (QRB), quarterly solo (QRS), annual branch (ARB), annual solo (ARS), annual ECB solo (AES), annual ECB branch (AEB), quarterly group (QRG) and annual group (ARG) returns, as a blocking check.

EIOPA’s own words and formula

In EIOPA’s list of validations, word for word:

si1559 doesn't follow LEI ("^LEI/[A-Z0-9]{{18}}[0-9]{{2}}$"), "^SC/.*" pattern, or "^None$" in case of natural persons.
