General information: firms must report either LEI or FRN and all fields must be populated (OF700.00.01.01, Bank of England check boe_b0954)

A blocking check on the general information template (OF700.00.01.01), in the own funds (PRA001) return.

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

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

In column "Header info" (0010) of General information (OF700.00.01.01): 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 OF700.00.01 as reported.
