Additional Process Information 
If you choose to store both the company code currency and the operating concern currency in CO-PA, the system creates two line items in the segment level (table CE3xxxx, xxxx = operating concern) for each actual transaction that is updated in CO-PA.
The values are transferred directly from the original document in their respective currencies wherever this is possible. If the values are not available in the required currency, the system translates them from the transaction currency using the current exchange rate valid on the posting date.
