Warning
For some documents you will not have the “Due date (new)” field editable meaning that you will not be able to change it though this transaction. This can be due several reasons which the most commons are related to the fact that it is a credit note already due or a document with special g/l indicator. In these cases, an IS ticket should be created asking IS to proceed with the change (we should assure that the date is correct in WARP and local system).
