How can I default the quantity of the PO during receiving fro mobile application

Create a PO with quantity 10

try to receive the PO in core application

during receiving the quantity of the po is displayed and perform receive just to select the line

now create a PO with quantity 20

try to receive the PO in mobile application

the quantity of the po will not display

I have to enter the quantity and not able to see the PO quantity

So how can I display the PO quantity using mobile application like core application
