At Payment Time, you must select the documents to be paid. At this moment, the system determines which withholding tax types and codes will be applied to the payment document. Once this process runs, the system calculates withholding taxes for the documents being paid. All these documents will share the same clearing date, but their posting dates will correspond to their original posting dates. As a result, the payment document will have the same clearing date and posting date. The only exception is when the payment document is reversed. In such cases, the reversal also updates both the clearing document and the clearing date of the documents originally paid by the payment document.
