This has no other effect than setting the resource automatically on 
transaction you create (using init script). Some "bad code" may remain 
assuming that currency is the one from preference, but the accounting 
currency is set on the organisation (with 'price_currency' category).

If you don't set the converted value ('asset price' in ERP5 technical 
vocabulary),  the system assumes that the converted value is equal to 
the non converted value ('quantity'). Accounting reports in "local" 
currency uses asset price.
So this default is fine for most of the cases where the asset price is 
the quantity, because the resource on the transaction is the accounting 
currency for the organisation.
But there are no constraint to force setting the asset price on a side 
when resource is different from accounting currency on this side. It's 
probably a bug.
