For RFF a fund number must be reported in Solvency Capital Requirement - Non-Life underwriting risk (SR.26.05, EIOPA rule BV634-2-1)

A blocking check on the solvency capital requirement - non-Life underwriting risk template (SR.26.05), 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 - Non-Life underwriting risk (SR.26.05)

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs eight of them (BV634-2-1-1 to BV634-2-1-8), and a failure names the one that failed.

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.26.05 as reported.

The cells it reads

Solvency capital requirement - non-Life underwriting risk: non-life premium and reserve risk (SR.26.05.01.01)
