Basic information: there should be no new line or tab characters for name string type fields (S.01.02, S.08.01, S.06.02, EIOPA rule TV64)

A warning on the basic information (S.01.02), open derivatives (S.08.01) and list of assets (S.06.02) templates, in the quarterly solo (QRS), quarterly group (QRG) and quarterly branch (QRB) returns.

The rule in plain words

There should be no new line or tab characters for name string type fields

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs six of them (TV64-1 to TV64-18), and a failure names the one that failed.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the code or text in your return with the format the rule sets out, character by character, including any prefix and any spaces.
  3. 03This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
