Need help in achieving a particular planning scenario

Hi,

We're implementing Capacity Planning and MRP (not ASCP) for the first time and would welcome any suggestions on how to achieve this particular planning scenario:   Based on a demand of 20, instead of generating 1 work order of qty 20 that takes 1 month (20 business days with a LT of 1 day per unit) to complete, would like to create 20 work orders, all starting on the same day and still finish after 1 month (same duration as before).   We've thought of configuring a Fixed Order Quantity of 1 against the finished good.  MRP would generate 20 work orders
