Regarding Inventory Pick

Hi forum,

i have a small issue. i have created a released production order which has 10 items as Bill of materials and trying to create a inventory pick. Inventory Pick has been created for all the items except for one item. That item is there in inventory and also the shortage list is showing blank but still inventory pick is not getting created for that item so could you please help me out in this as our client is on live.

thanks in advance
