SAP SD Picking option in display

Question
I am trying to create delivery but the picking option is in display" why?

Hi Mandeep,

The probablity says that you must be trying to create the delivery with standard data, the picking option is greyed out because the delivery needs shipment and picking would happen through creation of shipments (VT01N) or through transfer order (LT01). The standalone delivery document would not allow you to create picking.
