Share of reinsurers (including finite reinsurance and SPV's): double, trailing or leading whitespaces are not allowed (S.31.01, EIOPA rule TV49)

A blocking check on the share of reinsurers (including finite reinsurance and SPV's) template (S.31.01), in the quarterly solo (QRS), quarterly group (QRG), quarterly branch (QRB), annual solo (ARS), annual group (ARG), annual branch (ARB), financial stability solo (QFS), financial stability group (QFG) and financial stability branch (QFB) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

Double, trailing or leading whitespaces are not allowed

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
