Update Delivery qty on Inquiry

Question: The delivered qty is basically updated on order that the delivery made
from. It supposes to update on ref inquiry that the order created from
as well but we found that it doesn't although the copy control settings
between enquire document type and order document type is in place.

Answer:
I got feedback from OSS that is the standard design of the system. The delivery quantity is reflected to sales order, but not to Inquiry or Quotation.

Well, my doubt is why the 'delivered qty' field appears on inquiry schedule screen and SIS standard event 'VG' also contains the field available to conduct the value. There must be a reason to keep it on the screen both for inquiry and quotation.

I believe that an agreeable solution will be found upon this issue.
