I may be wrong, but I think this report doesn’t use the ILE, or Value Entry table, the cost will be that which is on the Sales Line at time of posting.
As I said I may be wrong, but I think that this is why there is no adjustment.
The statistics are not updated after cost-adjust. But in NAV 5.0 a work-around is made so that you can see “Original cost” and “Adjusted cost”; this is made by using calculated sums, not table-fields. In versions older that 5.0 you only have the original costs and profits.
