Changeover in Costing-Based Profitability Analysis 
Purpose
The currency changeover in Profitability Analysis (CO-PA) is carried out exclusively using the EURO conversion tool. This program converts all the currency-relevant CO-PA tables by completed fiscal year.
No program modifications in CO-PA are necessary. Moreover, special programs are available for providing the conversion tool with the information necessary for the conversion. These programs are executed automatically. All you need to do in CO-PA is carry out the preparation and cleanup manually (see the relevant sections in the IMG for European Monetary Union).
Process Flow
The following CO-PA specific programs are called up during the corresponding phases of the general changeover:


Brief documentation has been produced for each of these programs (transaction SE38 - Enter Program Name - Display 'Documentation'). This can be if errors occur, for example.
The WAERS field in table TKEB contains the currency for tables CE1xxxx, CE2xxxx, and CE3xxxx in operating concern xxxx. The conversion tool uses this table to interpret the values posted in tables CE1-CE3, and then converts those values into the new currency (euros). Likewise, the exchange rate (field KURSF) in the actual line item table CE1xxxx is converted to the new operating concern currency. The summarization levels contained in the operating concern are also converted. Then the new currency is entered in table TKEB.
If your data in CO-PA is updated in both the operating concern currency and the company code currency, these values are distinguished by the field PALEDGER in tables CE1-CE3. These records are translated to the new currency (euros) if the corresponding company code is converted. This is also true for any existing summarization levels.
Also, the field REC_WAERS, which stores the currency of the line items posted in Profitability Analysis starting in Release 4.0, is converted if it is not empty. This applies to line items that were posted before Release 4.0.
Result
The following tables in costing-based CO-PA are converted during the currency changeover:
Converting Stored Report Data
Constraints
Report data is only converted in costing-based CO-PA for reports that only contain data in the operating concern currency!
Report data for reports that display both the operating concern currency and the company code currency is not converted. You can find further information in the IMG for European Monetary Union, under Local Currency Changeover ®
Cleanup ® Cleanup in Controlling ® Cleanup in Profitability Analysis ® Reconstruct Report Data.Process Flow
Report data is converted after the central changeover, following the so-called "system lock" in the POST phase. The report data is then automatically changed over to the new currency. This applies to both "frozen" report data and summarization data.
All reports are regenerated during conversion. Exceptions in reports are likewise converted.

You cannot call up any reports until conversion of the reports has been completed.
You can find further information about converting reports in the IMG for European Monetary Union, under Local Currency Changeover ®
Condition Tables
Condition tables are not converted, since it may make sense to keep the condition records in the old currency. An example of this would be if you have customer-specific conditions for customers that still use the old currency.
You can handle condition tables in a number of ways following the currency changeover. For more information, see the IMG for European Monetary Union, under Cleanup in Profitability Analysis ® Process Conditions (Costing-Based CO-PA).
Rounding Differences in Translation
Because line items and totals records (and segment level) are converted separately, inconsistencies may arise due to rounding differences.
These rounding differences do not impair the functionality of CO-PA and so do not pose a problem that needs to be resolved. This problem does not arise with data posted after the conversion.

Two actual line items are posted in table CE1xxxx that are merged to form one totals record in the segment level CE3xxxx.
The exchange rate for the currency conversion is 1.81238 DEM/EUR.
