The rule in plain words

For RFF a fund number must be reported in Solvency Capital Requirement - Health underwriting risk (SR.26.04)

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.26.04 as reported.

The cells it reads

Solvency capital requirement - health underwriting risk: total NSLT health premium and reserve risk (SR.26.04.01.04)
