COPA0004 Change in Exch.rate type

Question

Hi,
We’ve a costing based CO-PA in our instance which is shared by other co.codes in our environment. Now, with new business requirement, we
may have to use a separate exchange rate type for CO-PA than M. We’re trying to achieve this with exit COPA0004. We’ve also read the note 429517 on Currency translation billing document -> CO-PA to understand the value flow to COPA.
Please note that we don’t want to affect current exch.rate settings of existing co.codes which is ‘M’. However, for a new co.code we want
to move values to COPA with ‘P’ exchange rate.  
Question-
Is it possible to achieve it through user exit COPA0004 to default exchange rate in COPA based on company code? Or is it a blanket change
for all co.codes if we change the rate from ‘M’ to ‘P’. 
We’re evaluating the solution before implementing in system.  
Thanks,
Nirav

Hello Nirav,
planning version settings in CO-PA do only affect planning data!
Conversion with actual data will always be done with rate type 'M'.
Enhancement COPA0004 offers however a possibility to use different
rate type in case of actual data.
Function module EXIT_SAPLKECU_001 can be used to change the exchange
rate type for currency translation when actual data is processed in
Profitability Analysis. By default, the system always translates the
values using the exchange rate type "M". You can change this type
(export parameter E_KURST) for a specific operating concern (import
parameter I_ERKRS). The import parameters I_CURRENCY_FROM and
I_CURRENCY_TO contain the currency key of the currencies involved in the
translation.
You can only change the exchange rate type for translating actual
values! For planning, you specify the exchange rate type in Customizing
when you define your plan versions.
