Make to Stock

Hi Friends,

My scenario is Make to Stock(MTS) scenario.

I have 3 plants: 1000,2000,3000

Stock available in plant 1000: 20 Pcs

Stock available in plant 2000: 200 Pcs

Stock available in plant 3000: 800 Pcs

Example: I am creating the order for 50 Pcs..

1) if the order is for plant 1000 it will confirm only 20 pcs and what will be status of the 30 pcs..when i will confirm that 30 pcs?

2)While creating the order(from the order screen) can i check the stock in different plants? so that i can select the plant which is having the sufficient stock.

with regards
