How to transform data in the second cube

Question

Hi,
I have been given this scenario where I have to load from one cube into another cube.
The data in first cube is in three currencies
LC      GC      TC
100     200     300
Now when I load this into second cube, I want to insert currency type infoobject and get the result as
Currencytype          Amount
10                     100
20                     200
30                     300
I would greatly appreciate if you can give me your thoughts on how to do this.Looking forward to your inputs.
Regards,
Kal

Hi Kal,
You have to options:
1. To have 3 KFs and 3 currency key accordingly.
2. You have 3 KFs only in the first cube. Knowing in which currency every KF is nominated you can easily determine a currency type and write it into a separate infoobject (there is business content infoobject 0CURTYPE).
In the 2nd cube you'll have a currency type IO and one KF for amounts.
In the start routine of the update rules you'll have to triple every record.
You’ll map your amount KF in the 2nd cube with, for example KF in Group currency. The routine will add two more records for the other currencies.
It would be easier to have in the 1st cube 1 KF and currency type. In this case you wouldn’t need any routines and mapping would be 1:1.
However, all this ways have a drawack. – If you need to report on some particular currency, you don’t have this info in the cube.
And as wrote in the previous posts, group currency may differ from group to group. Would you like to mix apples and oranges?
And finally, the generally used approach for such tasks is to have 3 KFs and 3 currency key chars:
