Thanks for the reply, SheandL albeit the normal canned one.  I've already sent a feedback submission which is useless and goes nowhere.  What I'd like to be able to do is open an actual support ticket for this bug as a paying customer, not a suggestion for enhancement.  I don't want an enhancement for a bug.

What needs to be told to the "engineering team" is that if you allow sales price to be 4 decimals with no rounding then you should also have new price the same way as it replaces the sales price on invoices.  This is a simple fix.
