System couldn't determine the source storage Bin

Dear Experts,

I've created the warehouse task for the outbound delivery order for an item 10. But when I try to create the warehouse order, I'm getting an error message that "System Couldn't determine the source storage Bin". Could you explain me why am I facing this problem?

I've checked the customizing. It is good. There is nothing to modify. It is due to some other reason. If anyone know the solution. please suggest me a solution.

It is really urgent. I'm facing the same kind of issue for many Outbound Delivery Order.
