Rounding off Unit Price

Hello,

Is there any config that i can deactivate the rounding off for unit price.

Sample

              PO 100 pcs ,                         unit price 98

Discount /pc    9.75%  (9.555)             unit price 88.445

Standard SAP will round the unit pricess to 8.45

Is there any config that rounding will not happen and the unit price become 88.44 ?

Thanks in advance.
