Attention: Whenever you recompile an ABC analysis or change the method by which you assign your ABC classifications, you lose any changes you might have made to your item assignments. All items are reclassified based on their new ranks in the ABC Descending Value Report and the method you choose to determine cutoff points.
You can also update an ABC group to include those items that were not a part of the initial ABC compile. This allows you to expand the scope of your existing ABC compiles without having to rerun any processes. For example, if you start stocking a new item in your inventory, you can make it a part of your existing ABC groupings through the update process. Otherwise, you would have to start all over by recompiling your ABC analysis and reassigning your items to ABC classes. With the whole process starting from the very beginning, you also run the risk of losing any changes you might have made to your item assignments.
