Purchase Order History-Amount GR with statistical conditon

Hi,

Displaying a Purchase Order History, can see that that Amount of on GR
is79.239.600,00 AON.

Still the true amount received is 68.904.000,00, as we have on statistical condition of
10.335.600,00 and it is not used to calculate the price.

We ask for your support, in order to tell us if there is any other way
to show the true amount in GR, I mean, the value without this
statistical condition.

Thanks for helping,

Maria
