What does the message mean?
This error may occur when the transmitted receipt contains a parameter outside the accepted limits. In the documented case, the common cause is the use of the VAT index. 0, which does not exist in the device configuration.
Check VAT indices
- Read the table of VAT rates programmed in the cash register.
- Associate each rate used by the sales application with the corresponding index in the device.
- Correct the receipt before resubmitting it and check the status of the receipt that is already open.
The index is not the VAT percentage
The old table with the percentages 19%, 9% and 5% described a historical configuration. Do not copy it automatically: use the rates and indices currently programmed on the equipment; confirm with the distributor.
