MREL Debt: a value must not be more than another (BR01.00.01.01, BR700.00.01.01, Bank of England check boe_b4106)

A blocking check on the MREL Debt (BR01.00.01.01) and general information (MRL003) (BR700.00.01.01) templates, in the MREL debt (MRL003) return.

Line4 Check runs it on the MREL debt (MRL003) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

The date of issuance shouldn't be later than the reporting period end date for this submission. If there is no date of issuance, please enter 01/01/1900

In MREL Debt (BR01.00.01.01): "Date of issuance" (column 100) must not be more than "Reporting Period End Date" in column "Values" (row 060, column 010) in General information (MRL003) (BR700.00.01.01).

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark BR01.00.01 and BR700.00.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
