If entity reports by RFF or uses MAP then Content of the submission [RFF/MP/RM] has to be reported (IRR.01.01, IR.01.02, Bank of England rule IR_bv0908_01)

The rule in plain words

What to do if your return fails it

1. 01Open the tables 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.01.02 and IRR.01.01 as reported.
4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Which returns it applies to

Line4 Check runs it on annual solo (ARS) return on Bank of England taxonomy 2.2.0. The Bank of England applies it to annual solo (ARS) returns, as a blocking check.
