Fixed Asset-entry with Service Tax

We are facing the below problem in Fixed Asset Module in R2 CU7.
In R2 CU7 version while we acquire an Asset through Purchase Order with Service Tax, system posting the necessary entry and the acquisition price and Service Tax amount calculating and showing the correct values in the necessary GL account based on our setup but if you check in the Fixed Asset module in an particular asset the system showing the acquisition price including service tax amount.

For example if an Asset purchasing the value Rs. 100 and Service Tax Rs. 12.50 if you do this transaction through Purchase Order system showing the necessary entry as below.

Fixed Asset Dr. 100

Service Tax Dr. 12.50
Vendor Account Cr. 112.50

But in this case while you check in a particular Asset it is showing acquisition price Rs. 112.50 instead of Rs. 100. It is wrong.
But the same entry in R3 version showing correctly and if you check in the particular Asset acquisition price showing as Rs. 100. It is correct.
Anybody have the solution pls. share…
