Conversion PRQ to ODA

Hi,

I entered in a purchase requisition for a material a price of 10.

When I create the purchase order with reference to the previous purchase requisition, system doesn't take as price 10 but 7.

In the purchase order I can also read the number of an inforecord.

If I click on it I cannot read any price....

Don't understand why system takes into account 10 of price instead of the one I entered in the purchase requisition (7)

Please help!

Thanks

Best regards
