When an invoice is imported into the PayablesInvoiceImport tables, where is the configuration to determine whether an invoice is a duplicate or not? In other words, I know there's some place in the system that defines the combination of variables that define a duplicate invoice. For example: Is it COMPANY + VENDOR + INVOICE# ? Or is it just VENDOR + INVOICE# ? I know somewhere there's a setup to define this - but I cant find it. Thanks
