The item "External rating" in List of assets should not be reported in case "no rating available" was provided in "Credit quality step" (IR.06.02, Bank of England rule IR_bv1776_02)

The rule in plain words

What to do if your return fails it

1. 01Open the table below and find the cells the rule reads.
2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
3. 03It runs only when your filing indicators mark IR.06.02 as reported.
4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

Line4 Check runs it on quarterly group (QRG) and annual group (ARG) returns on Bank of England taxonomy 2.2.0. The Bank of England applies it to quarterly group (QRG) and annual group (ARG) returns, as a blocking check.
