Rounding Differences in Billing Request Documents (BRDs)

Question

Hi:
Here is the scenario:
We are a professional services company. sales orders has WBS assignment for expense and time booking. Then we run DP91/DP96 to generate the BRD's.
Our issue is:
Lets say its a foreign currency contract (Sales order in AUD), local company code currency is USD and so is WBS currency.
Employee enters expenses on WBS in AUD currency which are transferred to WBS in USD (As local currency of employee). BRD process again converts the expenses from USD to AUD. Thats where the rounding differences are coming up.
For example:
WBS - (in USD)
Sales Order / Billing - (in AUD)
Employee company code currency / Same as WBS company code - USD
Expenses - 1000 AUD
Exchange rate from AUD to USD is 1.66961
So expenses are posted as 598.94 USD (1000/1.66961)
DP91 picks the WBS expenses (USD) and converts into billing currency (AUD) - 598.94 * 1.66961 = 999.99 AUD
So 1000 AUD expenses showed in billing as 999.99 AUD.
Though the difference is not material but some of our goverment clients are very particular about this. They dont accept 999.99 invoice backed by 1000 expense.
Please advise, is there any standard way to change BRD process to say if expense currency (which is AUD in this example) is same as billing currency, dont convert via USD (Which is employee local currency) OR any enhancement of DP91?
Thanks,
Rahul

Hi:
Thanks for pointing this note.
As mentioned in this note, our system is behaving the same way and converting the CO cost in transaction currency into billing currency. In CO (WBS line item report), transaction currency is the employee local currency when expenses are booked to that WBS.
System is behaving as per standard design.
I wanted to know if there is any enhancement we can write on top on this note to not look at transaction currency. The enhancement would look at the expense receipt currency and compare it with the billing currency. If both are same (regardless of transaction currency), dont convert via transaction currency.
May be for that matter I should check if there any way to transfer receipt currency as transaction currency in CO (instead of local company code currency as transaction currency)?
Just wondering how SAP internally or any other consulting companies are handling this conversion difference when billing to their clients?
Thanks.
