Sales order item not showing in picking list

Hi All

After confirmation of whole sales order quantity and deliver the partial order does it required to reconfirm the sales order of the non delivered items.

As i did the partial delivery and in the confirmmation the pending items are showing but in the picking list the whole items are not showing it is showing the 1 out of 3.

Can anyone tell why is it showing only one.

thanks

Depends upon what you have delivered, the parameters of the pick and the configuration of elements like reservation. No confirmation is required in sales.
