Hi Susan (and Steve),

While it goes without saying that transaction posting should update the "last activity" date, what other activities should do so as well? How about entering a note, or changing a contact? Updating an address or phone number? What about moving transactions from current to history or sending a statement (which may generate an automatic note)?

As Steve pointed out, you can use GridView or the SmartFinder to generate a list of customers you'd like to inactivate. Just re-import the customer codes and default the Active flag to "False" in the import template.
