template of a rolling forecast for production?

[Guest]

We need a rolling forecast schedule template at work.
We have an 8-week cycle, in which forecasted quantities of items are
"frozen" or committed. I need something that will populate or roll in each
new week. Help!

I think we will need a little more information then that.

8 week commitment to buy. First four weeks commit to buy and ship. Second 4
weeks customer commits to buy but can defer up to 25% of its shipments up to
60 days. We need a spreadsheet that shows the 8 weeks and somehow rolls the
calendar weeks forward, along with their part quantities (about 20 parts).
Qtys must stay fixed as week 5 rolls in and becomes Wk 4. Wk 9 can be a best
estimate of qtys to be purchased, but as Wk 9 rolls forward and becomes Wk 8,
qty is fixed in sales but ship qty can vary up to 25% of what it was in Wk 8.
Make sense?
