3rd party- SD cost in billing not carrying the price for vendor

Question

Hi all,
in SD billing VF01(to customer),the cost for buying the material form vendor is prompted. The cost will take the price in the PO for vendor. Example there is 2 item. A -price 1, B - price 2. Both of the materials are being GR PO on the same date, but the invoice verification (MIRO) sometimes is posted partially- item A first, then item B.
The problem is here, when the partial invoice verification is done, the cost in SD billing will only take price of item A while the qty is a summation of item A & B.
Can anybody explain why is this happening and how can we avoid this..
Thank you.
