Ktran -

You say you have the part numbers and the time it takes to make each one.
How is this time stored? If it is in decimal hours (e.g. 2.5 = 2 hours 30
minutes, 0.75 = 45 minutes, etc.), then you can multiply the number of parts
needed by the hours per part. You can do a VLOOKUP from the sheet giving the
quantity and due date into the sheet with the part numbers and time to get
the time per part, and multiply it by the number needed.

If you need more help, give us more details, and where your struggle is.
