Determination of Invoices and Payments

In order to prepare the list of customer invoices and payments, the Sales Ledger report proceeds as described in the following.

Activities

First, the report reads all tax-relevant documents (tax transfer documents, invoices with target tax codes, and down payments), and determines which invoices and payment documents relate to them as follows:

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 invoices with target tax codes, the number of the payment document is stored in the customer item.
In the case of down payments, the payment number counts as the invoice number as well as the payment number. The report does not mark down payments as such, nor is this required.
