Some organizations have short billing cycles (e.g. weekly). They create multiple Delivery Notes that will need
to get first confirmed by the clients before an invoice can be created.
The feature to be created should provide user with the information, for how many units of a task a Delivery Note has been created.
Suggested Extension:
New wizard "Create Delivery Note based on Time Sheet Tasks" which works the same way as "Create Invoice based on Time Sheet Tasks" but creates a Delivery Note
Add new column in wizard "Units in Delivery Notes (pending)" that shows all units that had been considered in a Delivery Note (see screen shot below)
Pending units for time sheet tasks need to be adjusted when
a) A Delivery Note has been changed or deleted
b) An Invoice has been created based on the Delivery Note
