Multiple GR values for same quantity

Question

Hello all SAP MM Gurus,
I have a strange problem. I have a MM scheduling agreement 5500013812 and in this agreement there is one line item for material 651660. The GR has been done for this line item a number of times since 2009. But when I went to purchase order history of this line item, I found that for a quantity of 500 PCs, the system has posted different amounts.
For example, when the GR was done on 02/21/2011 for qty 500, the amount was 706.68 EUR. When the GR was done on 01/31/2011 for qty 500, the amount was 776.94 and when the GR was done on 12/13/2010 for qty 500, the amount posted was 765.57 EUR. This is really puzzling me since there are no price changes in Material master record or in MM scheduling agreement. There are no alloy surcharge price changes also. But still, why the system is posting different amounts for same quantity of this material, I don't understand.
Can someone please tell me whether I am missing something somewhere? Your suggestion would be very much helpful for me in resolving this issue.
Thanks and Regards,
Umakanth
