The rule in plain words

Firms must indicate either LEI or FRN and all fields must be populated

In column "Header info" (0010) of Header Info (SC700.00.01.01): either "Firm reference number (FRN)" (row 0020) is reported, or "LEI code" (row 0021) is reported, and exactly 5 values must be reported in 5 rows (listed below).

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 SC700.00.01 as reported.
