Check your file for this rule

The rule in plain words

Transitional Measure on Technical Provisions must be equal to TMTP risk margin, best estimate dynamic and non-dynamic components minus TMTP amortisation adjustment

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.

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 IR.12.01 as reported.
