Occasionally in the Fixed Assets module you see a scenario in which you perform a purchase increase transaction from the Asset Transaction (FA.020.00) screen but find that the cost of the asset is not correct in the Assets (FA.010.00) screen. If this is the case, you may have entered a purchase transaction manually for each book rather than a transaction without a book code to update the asset as a whole. This action will create an OVERRIDE entry.
OVERRIDE entries are meant to update the cost for a specific book while the main asset itself retains the cost that affects all books.
To avoid this scenario, leave the Book Code field blank on the Asset Transaction screen when entering transactions to adjust the cost of an asset.
