Is there any reason why there is no threshold at all? The validation BV870 requires an exact match (on Euro cent level) whereas the two amounts compared could be double digit billion Euro numbers. From our perspective a validation tolerance need to be implemented for all blocking validation rules.
The validation will be deactived. We will analyse by the next 2.5.0 taxonomy release for which validations an exact match will be required and for which a tolerance will be set.
