Change of Group

Hi,

I has defined few Item Groups and assigned the Item Groups to the Items and for the Item Groups the sub groups has been defined and assigned to the items.

Items-- ->Item Groups -->Sub Groups

And I has made the transactions such as PO, GRN, AP Invoice later I found that the for one of the Item the groups is not the correct one so i has changed the Group and sub group for the item. And I again i made the transaction same as above.

Now can i generate the report stating that what is the group and sub group for the item before change and after change.
