Lot/serial class cannot be changed when its tracking method is not compatible with the previous class and the item is in use.

Regarding this error there are a couple of customizations that users can try to fix this issue occurring even after clearing out the inventory and open transactional documents:

This didn't work for me though even then and I had to open a case with Acumatica.

It's still cumbersome to flush the inventory and bring it back in, but at least you'd be able to keep the item history.

I am unable to change a stock item's serial class. This is the error I get: 

Lot/serial class cannot be changed when its tracking method is not compatible with the previous class and the item is in use.

It seems to mean I cannot change an item's lot/serial class if they have different tracking methods. Is the only solution to recreate the stock item?
