Hi,

I have around 300 records on a object (which is a child object) having currency ISO code as USD which is wrong in first place because the values have been pulled from another object with right currency code for calculation however the values have been stored in this child object with Currency Code as USD. Now I would like to update these child records with its parent's Currency Iso code. When I tried updating single record, the currency values automatically updated to the converting currency code(say EUR). To make it in simple words, I want to update currency ISO code of a record without the values in currency fields updated automatically! 

Thanks,
Wahid
