R42950 is updating unit price on a split line with no volume discount

R42950 is being run prior to invoicing but after commitments has split the line due to multiple lot shipments.  Exchange Rate and Price Update are on.  The result is the unit price is recalculated based on each split line's quantity and not the original quantity entered. Processing option on R42950 to use the original quantity is on.  Do the processing option settings seem ok on R42950 so that split lines should not be re-priced on the split quantities?  Thanks.
