# InvoiceToleranceConfig

## Description

InvoiceToleranceConfig records one supplier-specific invoice tolerance configuration used during AP document registration. Each row is scoped to one company and one supplier SupplierAccount pair and relaxes the unit price and quantity variance checks that drive SYSTEM payment holds. Tolerance fields are optional: a null or omitted field means strict matching for that field, while an absolute or percentage value widens the accepted variance before a SYSTEM hold is planned.
