Never duplicate any derived information while the data object holding the duplicate is still in the system.

Only when this data is removed from the system you actually calculate and use the currency values. -W 2011/4/17 Riyaz Saiyed <riyaz.sai...@emirates.com> > Hi, > > > > I'm doing a POC on drools decision table.
