Confirmed Qty -2 Schedule lines

Hi Forum,

While creating order system generates 2 schedule lines confirming the products on a date in the second line .

Eg: I create an order on 17-09-2008 with qty 5 which gets confirmed on 18th-09-08 despite goods being available .

Lead time in days is blank and i have checked "Propose Delv Date" for the system to pick up current date as Delv date..

Thanks .
