Here you will see the rest quantity after reporting. The rest quantity is the difference between the Reserved quantity and the Reported quantity. The rest material is the quantity that remains on the order and reserves material after reporting.
If you want to delete the reserved material, enter a 0 in this field. The reserved quantity will then be the same as the reported quantity. You can also do this in Operation Reporting, by entering a 0 in the Rest quantity field if you have checked the Delete rest material option.
