SAP Message 5M058 - Car purchased more than 3 yrs after 1st registration. Do not use list pr.

Diagnosis
The car was purchased more than three calendar years after its firstregistration. To calculate the employee's imputed income, you must*not* use the list price of the car (that is, its value when new).Instead, you must use the car's actual purchase price.
However, the model and make of car have been specified, and a listprice has been entered in table T51C5 accordingly, so the latter isused for the calculation. This is normally an error.

System Response
The system displays a warning, but still accepts the list price.

Procedure
Delete the entries in the 'Manufacturer' and 'Model' fields, and enterthe actual purchase price of the car in the 'Purchase price' field.
