If we make any changes in Purchase order lines like cancelling the quantity, or partial receipt etc, the same not reflecting in purchase order total. Purchase order totals are not displaying correct details as per Line status.

Eg: A purchase order created with two line for 10 quantity and 5 quantity respectively. We have done the receipt for 10 quantity and cancelled one line for quantity 5 in the purchase order . But the amount which is showing in the purchase order total is for 15 quantity instead of 10 quantity.

This is a problematic situation when there is a workflow approval based on purchase order total.
