• Message text: SYST: &.

¿Qué causa este problema?

When calculating the taxes, an internal error occurred. The name of the
routine is stated in the error message.
If the error comes from the Routine LTAX1U04, the cause can be an
incorrectly maintained tax code. Check whether the tax code is
maintained correctly, in particular that the base values are defined
for the individual levels so that actual values can also be calculated.
Example of an incorrect definition:
Tax category Tax rate Level From level
Base amount 100 000
Output tax 10.000 300 200
Since a tax rate does not exist for level 200, the output tax cannot be
calculated.

¿Cómo arreglar este error?

Before you attempt to analyze the program, check the tax calculation
procedure you used for accuracy. Check whether the tax code used is
allocated to the correct tax type and whether a valid base value is
allocated to this tax type.
If you cannot solve the problem, consult your system administrator.
