There are many business processes which do not require or cannot use direct delivery to perform the daily activities, this is why the below referenced scenario is highly impacting the business processes.
When cancelling the deliver remainder on the original sales order, the chain is not synchronized as expected. Intercompany sales order and purchase order will still be open order. (this behavior has been investigated also via Issue 451633)
An option should be considered to accommodate such a business process as well.
