You have a report based on an InventoryTransfer table.

The expression that calculates the difference between the future EffectiveUnitTransferCost and the cost to transfer today would take the future cost and subtract the current cost converted to today's date, considering the transfer quantity. The CONVERTONDATE function is used to convert the historical TransferCost to its value as of today, and then this value is divided by Quantity to get the unit cost as of today. This unit cost is then subtracted from the EffectiveUnitTransferCost to find the difference.

ReferencesThis uses the CONVERTONDATE function in Kinaxis RapidResponse, which is designed to adjust historical cost figures to their equivalent value on a different date, accounting for factors such as currency fluctuation, as outlined in the Kinaxis formula and functions documentation.
