I'm trying to figure out what PS does to adjust for total value discrepancies between an invoice voucher and associated PO. Say on my PO I have a line item with quantity of 2 and unit price of $10. Therefore total value is $20. When I create a voucher, that same line item is now 2x$11 = $22. I approve that voucher for $22. Now I run the Extract Landed Cost batch process. What does this process do to "compensate" for the difference between voucher and PO? Does it change the unit price of that item in inventory from $10 to $11?
