You can make changes to a down payment request by changing the document or the line items of the customer, vendor or reconciliation account (special G/L account). Changes are necessary, for example, to remove a payment block or to change the due date.

You can find further information on changing documents or a series of line items in FI - Document Posting.

To change line items in a customer or vendor account, you must select With special G/L transactions in the initial screen. Otherwise, the down payment requests are not selected for line item change.
