Would appreciate if anyone can help me to understand how master planning calculate the requirements date. Example:- I have a production order #100, Item A and the BOM item is B. (Details for B item : On-hand = 10 , safety stock(minimum) = 15 , Open order that needs item B = 5 , Coverage code = Period Coverage, period = 20, Purchase Lead time = 30.) When i run explosion in production order (on 01-Feb-2013), I got the result for item B with a planned purchase order, qty=10 and the requirement date is 3-Mar-2013. Item A future date = 3 Mar-2013. In fact, I still have available physical 5, why system take the planned purchase order date (3-Mar-2013) and not today's date? Any setting that can resolved this problem?
