2009.2 computes commission differently, we suddenly owe reps thousands

Folks,

When I went to authorize this months commissions, I found that I had commissions due to our sales reps dating back to the day we first started using the commissions module.

Once I got over the panic of the thousands of $$ owed and dug into the transactions, it became clear that the commission due was a small delta from what was previously authorized. NetSuite was doing the commission calculation differently now, throwing off the entire history of previously authorized commissions.

Digging deeper, it seems to come down to the costing of drop-shipped POs. In 2009.1 NetSuite used the actual cost of item that was actually fulfilled - the purchase/billed price of the drop-ship purchase order we submitted to our vendor. I have traced about 10 transactions in detail and they all show this pattern. But now in 2009.2 it's just using the item cost that's defined in the item record. We fulfill from 4 or 5 different vendors, all with different prices, so it's the actual cost that matters to us ... the item record cost is pointless and incorrect!
