# Variants data set

> Variants data set columns for commercial invoice processing, mapping vendor details like VATID, IBAN, and address to Document Definition fields.

The **Variants** data set contains information about vendor companies. This data set is used for detecting the issuing company and checking extracted issuer information against a database.

<Note>
  Information from external databases can be used to facilitate the detection of company details on commercial invoices. Additionally, [field training](/flexi-capture/invoice-reader/ir-operator-training) becomes available if external databases are used. If no external databases are used, ABBYY FlexiCapture will use its built-in neural networks to detect company details.
