Does anybody know of a good way to track profitability on purchases?

In Power BI we've aggregated related records to show true profitability on transactions such as Sales Orders. But this was not possible inside of NetSuite. Let me know if you want more details.

i would love some more information. We currently are looking at serial numbers that were received from a PO and looking at all sales and returns associated with the serial number, but the way we are doing this is not very efficient so I would love some better ideas
