Please update how to create partial delivery note.
Sales Order / Sales Invoice > Create button > Delivery Note.
- Select rows which you don’t want and delete them to make a partial delivery note.
- Alternatively reduce qty if you’re receiving partial qty of any line item.
- Do not add a new row manually. If splitting a line then “duplicate” it instead (to preserve references)

how to add delivery notes until full fill the ordered quantity in relevant sales order and after complete the quantity it should denies to add delivery notes to it
Check over/under delivery settings. Google it if you cant find it.
I would be carful creating delivery note from Sales Invoice. It could result in an inaccurate gross profit reporting. The best thing is to create delivery note from sales order, then sales invoice from delivery note.
