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

Procedure
Execute an interim billing at the time of the change.
