Validation rules

The KNF publishes the checks it runs on this return. They could not be counted from the published material. They are written for people to read; software cannot run them as published. Source

How they are written: Record layouts, field types and general rules in the PDF format document.

The DF format sets the field types, the header and footer records, the record count and the file checksum; corrections are sent as a full corrected file.

The rules, on sprawozdawczosc.knf.gov.pl

Counts are in the KNF's own unit, so they are not comparable with other regulators' counts.
