In MD04 The client getting PO line after the vendor confirmation, As it should not shown in MD04.
The PO line should be visible only when the open PO quantity exist, for example PO ordered quantities are 5nos, and the vendor confirmed only 3nos then MD04 should show PO line along with the shipment notificationline.
But In this case there are no Open PO quantities vendor confirmed all 5nos Although the PO line getting visible in MD04. This leading the miscalculations for client as the requirement number appeared as confirmed quantity in PO line
