Every Solvency II validation rule, in plain words

Every validation rule Line4 Check runs on EIOPA taxonomy 2.10.0, in plain words: 368 rule codes for the quarterly solo, quarterly group and quarterly branch returns (QRS, QRG and QRB). Search for the code in your rejection message, read what the rule means and what to do, then check your return in your browser.

260 of the 368 rules are blocking: a return that fails one is normally rejected. The other 108 are warnings: they do not stop a return, but your supervisor may ask about them.

How these pages are written

Every page is written from the rule Line4 Check runs, compiled from EIOPA's taxonomy 2.10.0, and from EIOPA's list of validations, with the row and column names of EIOPA's templates. Nothing is guessed. The plain words are EIOPA's own, with each template's code moved after its name; EIOPA's formula follows them on every page.

EIOPA writes many rules out as several checks, one per table or return (BV1015-2, BV1015-3). Each rule code has one page, and a search for any of its checks finds it. Line4 Check does not run 148 of EIOPA's other rule codes for these returns yet, so they have no page here.

Checks like this one, run at the point of submission, are the first step to real-time supervision.
