Picking Quantity is not determined automatically in the Delivery

Hi All,

Automatic picking quantity is not working.

No Wm module is implemented for the delivery

How the Picking Quantity will be determined automatically in the Delivery, Now we are entering the Picking Quantity manually in Picking Tab.

Actually my client process is creates deliveries from vl10a and goes to vl06o picking tab here they selects a variant and there enters sales area and group the deliveries here they wanted the picking to be done automatically and goes for again post goods issue tab and enter the group number but the delveries are not displayed as they are not picked

Please Suggest.
