Dim:GO doesn't follow "^LEI/[A-Z0-9]{{20}}$" or "^SC/.*" pattern (S.37.01, EIOPA rule BV1232)

A blocking check on the risk concentration - exposure to counterparties template (S.37.01), in the quarterly solo (QRS), quarterly group (QRG), quarterly branch (QRB), annual solo (ARS), annual group (ARG), annual branch (ARB), financial stability solo (QFS), financial stability group (QFG) and financial stability branch (QFB) 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

dim:GO doesn't follow "^LEI/[A-Z0-9]{{20}}$" or "^SC/.*" pattern

What to do if your return fails it

  1. 01Open the table 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. 03This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Risk concentration - exposure to counterparties: risk concentration - exposure to counteparties (S.37.01.04.01)
