Display changes in Reorderpoint

To analyse historic data I need an overview of the changes that have been made ithe reorderpoint and an overview of the actual delivery time. Is there an easy way of extracting this? At this moment I look up all the changes that have been made on the reorderpoint with MM04, but this is a lot of work because i have to open all the material changes to see whether the change is a change on the reorder point. If you know a better way, please let me know!
