I use "Run Scheduler" to generate Draft Purchase Orders from my Sales Orders.

If I am buying in (EUR) and my base currency is in (GBP), I get a problem that my draft Purchase Order Currency field = (GBP) (when it should be in EUR) and my pricelist is correct in (EUR). I have been through all the forums and there seems to be some criticism that OpenERP cannot handle purchasing in multi-currencies. Is this part of the same problem?
