Determination of Invoices and Payments
In order to prepare the list of vendor invoices and payments, the Purchase Ledger report proceeds as described in the following.
First, the report reads all tax-relevant documents (tax transfers, down payment clearing documents, and tax adjustments), and determines which invoices and payment documents relate to them.
In tax transfers, the report reads the number of the invoice and the number of the payment from the Reference and Assignment fields respectively. If the Assignment field contains a clearing document number instead of a payment document number, the system uses the payment date and number from the first payment item in the clearing document.
In down payment clearing documents, the down payment is the payment; the invoice number is stored in the Reference field. If the Reference field contains anything else, the report displays the down payment clearing document number instead of the invoice number.
In the case of tax adjustment documents, neither an invoice nor a payment exists, and so the report displays the tax adjustment document number in the invoice and payment document fields.
