For RFF a fund number must be reported in Solvency Capital Requirement - Counterparty default risk (SR.25.01, SR.26.02, EIOPA rule BV576-2)

A blocking check on the solvency capital requirement - for undertakings on standard formula (SR.25.01) and solvency capital requirement - counterparty default risk (SR.26.02) templates, in the annual solo (ARS), annual group (ARG) and annual branch (ARB) 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

For RFF a fund number must be reported in Solvency Capital Requirement - Counterparty default risk (SR.26.02)

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark SR.26.02 as reported.
