Assume the following scenario:
Sales order is created.
Delivery note is made against sales order in step 1.
Sales invoice is made against delivery note in step 2.
Return/Credit note is made against sales invoice in step 3 (and stock is not updated).
Following these steps, the status of the Delivery note created in step 2 will be To Bill.
Can someone please explain a use case in which having Delivery note status be To Bill is useful?
Under these circumstances, I can’t think of any reason why there would be a need to create another sales invoice.
