Since this question came up in 2020 I'd like to resurface it again with a twist.

Our situation is that we need to make an update to an Income Account for several part numbers (Type = Inventory Part) but we DO NOT want to effect any previous years of reporting.

In May of 2020 the answer says the change will NOT effect 'inventory' type item numbers.  Is this still the case?

Also, we are using QuickBooks Enterprise Solutions: Manufacturing and Wholesale 20.0 and I believe this person was asking about Quickbooks Online. 

HELP!  Thank you.
