Demand Planning

We are new to Native Netsuite, and we are wondering about some issues we have encountered with the Demand Planning process.

Does anyone have any insight to some/all of these questions?

1)       Is there a suggested flow for work order planning (ie: using scheduling tool/screen to convert planned WO to firm WO’s)? What is the canned NS business process.

2)       Is there a way to have sales orders automatically decrease/consume forecast?  We seem to have to replace forecasts with orders manually. Surely there is some functionality available that automates that to avoid double counting the demand

3)      Can we enter quote/pricing information?  What happens today is for a sales opportunity we go out and get quotes from suppliers.  Lets say a supplier quoted $0.13. Based on that we quote the customer say $0.20.  But when Purchasing needs to actually purchase that item we have found instances where we end up buying for higher prices than the quote.  Is it possible to create a quote in NS then create a PO from it? Or use notes, etc. to record that sort of information so the Buyer can easily see what was quoted.
