HI Tony2820
In testing this in AccountRight 2020.1 using a Clearwater file, changing the field and list names by going to Lists >> Custom Lists & Field Names >> Items The changes flowed through to the different inventory reports as expected.
If you were not seeing that information flow through as expected, I’d be inclined to clear the AccountRight cache. This refreshes a number of things in the background of AccountRight and should be sufficient to get those fields to update, assuming that the correct lists and field names have been updated.
