Not summarization position for base of withholdings

Question

Hi,
I created a bill with tcode VF01, and this document contains two positions:
1. Position 10, One material with VAT of 16%
    amount      4.462.965
    VAT             714.074
    Net value    5.177.039
2. Position 20, one material with VAR of 0%
    amount         120.000
    VAT                       0
     Net value     120.000
The customer have two withholdings types:
1. Withholdings Rent:   11%
2.  Withholdings Local:   0,8%
When i posting the bill, in FI generated the following document:
                                         Db                            CR
Customer ID                     120.000
Customer ID                  4.684.333
P&L                                                                  120.000      Tax code AE= 0%
P&L                                                               4.462.965      Tax code A2 = 16%
VAT 16%                                                           714.074      A2
Withholding 11%               492.706
Withholding 0,8%                35.833
                                    5.297.039                 5.297.039
The issue is as follows:
1. The base used for calculation of the withholdings, is wrong, because add the values of materials and prorrated the VAT, for find the base, so:
base = (4.462.965 + 714.074) - (((4.462.965 + 714.074) /(120.000 + 4.462.965 + 714.074)) * 714.074)
        = 4.479.142
and over this value, calcules the withholding:
11% = 4.479.142 * 11%  = 492.706
0,8%= 4.479.142 * 0,8% =   35.833
The correct calculation is:
base = (4.462.965 + 120.000)
        =  4.582.965
and over this value, calcules the withholding:
11% = 4.582.965 * 11%  = 504.126
0,8%= 4.582.965 * 0,8% =   36.664
The requirement is: how do modify this calculation? and not use the second position without VAT?
Thanks for you answer.
