Service rendered date in invoice

Question

Hello,
The problem i am facing is with the service rendered date at invoice item level. I  have created invoice through milestone billing plan assigned to the item category.The service rendered date is given in the order item level .
When i invoice the order the service rendered date in the invoice item level is the billing date in the billing plan, which is different from the service rendered date in the order.
When tax is determined in the order based on the sevrice rendered date in the order , where as the tax is redetermined in the invoice considering the new service rendered date.
Please inform the reason for the same and how could i avoid the problem . My requirement is that the service rend. date in the invoice should be same as in the order , not the billing date .
Billing type i am using is milestone billing and billing relevance in the item category is "I" order related billing_billing plan.
Thanks in advance
Kiran

Hi Kiran,
The behaviour being experienced is standard. The item category has
billing relevance of 'I'.
In this case, please check the following coding:
LV60AA93 -> FORM VBRK_VBRP_FUELLEN
move-corresponding vbkd to vbrp.        >>>>> VBRP-FBUDA filled
Main Program     SAPLV60A
Source code of   LV60AA93
FORM VBRK_VBRP_FUELLEN
if xfplt-fkdat ge xfplt-nfdat.
  vbrp-abrbg = xfplt-nfdat.
  vbrp-fbuda = xfplt-fkdat.  >>>> VBRP-FBUDA is overwritten here
else.
Since a billing plan is being used, VBRP-FBUDA is being overwritten by
the billing date of the billing plan.
This is the standard functionality of the system.
Please use the following workaround by controlling the date in the data
transfer routine.
Example coding -> VBRP-FBUDA = VBKD-FBUDA.
I hope the information is helpful.
