Help to modify MultiCurrencyTrans.LGL script

Question

We are working on this budgeting scenario:
For the input schedules, SKUs are budgeted per Entities. Budgeted sales price per SKU could be in any currency (currencies are chosen by the end user based on agreement with the sales department). Sample data are the following:
ENTITY 1
SKU 1
USD (or any currency chosen by the end user)
ENTITY 1
SKU 2
JPY (or any currency chosen by the end user)
ENTITY 2
SKU 1
EURO (or any currency chosen by the end user)
ENTITY 2
SKU 2
SGD (or any currency chosen by the end user)
Report output should have the budgeted original currencies per SKU per Entity as well as translated currencies into EURO.
In the SAP BPC MultiCurrencyTrans.LGL script, the currency translation works for a single LC to multiple currencies. However, in the scenario above, it works the other way around, i.e. data are in “multiple LCs” (i.e. sales price) to be translated to a single currency (i.e. EURO).
Can you help me in modifying the LGL script to meet the requirement described above?

Answer 1

One other thought that's a blend of the two above and would probably do what you're looking for is:
1.  I would do this as a separate application from any financial reporting applications you my have and push the LC over if needed for reporting.
2. Keep the currency translation dimension on the entity dimension with the correct currency property to identify what it's LC currency is.
3. Create the application with a standalone currency dimension (not used in other apps) that has all the members from the InputCurrency dimension in your rate application + add in LC.
4. Have users select the specifc currency that they're entering to (never LC).  So they'd pick Entity1, SKU1, JPY as an input point.
5. Write a custom FXTrans process that converts from the input currency to LC based on the entity.  I'd run this as part of default logic.
6.  Use the standard FXTrans process then to convert from LC into your reporting currency of EURO.  If this is the only reporting currency then the single currency FXTrans would work.  You'd want to make sure the code ONLY goes from LC to EURO.
So, users would enter JPY which would translate back to the LC of the entity and write the value to LC.  Then you'd translate from LC to EURO for reporting.  In cases where the  data entry is done in EURO, you'd go from EURO > LC > EURO but that shouldn't matter as long as you don't make any changes to the translation rates between the two processes.  HOWEVER, you need to be certain that if you change translation rates after data entry has occured that the process to go from input currency to LC is run so the LC values are correctly calculated or you would get different results when going to your reporting currency.
