I have this issue in PO pricing -
I hace created a PO with pricing details as under -
Basic - INR 10,000
Basic ED - INR 1600
EduCess - INR 32.00
Sec EduCess - INR 16.00
A/P -CST - INR 465.92
I goto ME22N, item Condition tab -
there I see NAVS = 400
(4% OF NET PRICE)
Next I goto Invoice tab & click on Tax
Again I come back to Condition tab & find that NAVS value is changed to 465.92
Also in EKPO table the field NAVNW is populated with 400 and not 465.92.
I think there is some problem with the behaviour of the system.
