PO generation not suggesting quantities

Hi,

for item A, my current available stock is  0.

Setup is done in Item BP ->buyer information -> Supplier value is set.

Also in item master : Order Policy Code= 0

In item BP ->Quantities :

Reorder Point = 4700

Reorder quantity = 300

Here, P43011 should suggest quantities. but it is not working.

Could you please suggest on the same.Please advise if we missed any setup.
