Payment Directives 
Some public organizations, such as those of Spain , Italy or Portugal , require an intermediate payment document that serves as a link between the financial department and the treasury of the organization. This document, called a “payment directive”, references a particular invoice and includes all the relevant information for the payment to be made. The following diagram illustrates the position of payment directives in the document workflow:

Note
You can create one or several payment directives for a single invoice using this transaction.
Payment directives are subject to a clearing process, as illustrated in the diagram below.

For further information see Clearing Process for Payment Directives .
The payment directives support invoices with withholding tax. You can get further general information on the withholding tax for payment directives in System Settings for Extended Withholding Tax , or information on withholding tax in Spain in Withholding Tax Reporting .
