Not permissible to change billing rounding from &1 to &2

What causes this issue?

The billing rounding has been changed in the register operands for both
devices/registers cited in the previous messages.
Both devices/registers have the same logical register number (this
usually means it is the same device/register).
The operand for the first register is &v3&. The operand for the second
register is &v4& (for the stated date).
A change in the billing rounding causes errors when rounding
differences are balanced in quantity conversion.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?
