Diagnosis
Once a certain number of years (1998 = three years) have elapsed sincethe car was first registered, a change of rules occurs that gives riseto two changes.
Cars purchased during the first phase before the change of rules arevalued after the change of rules using a reduced (1998 = 75%) listprice value.
Cars purchased after the change of rules are not valued using the listprice. They are valued using the current purchase price instead.
To calculate the value of a free car correctly, the system needs toknow the number of years that elapse before the change of rules occurs.This information is stored as constant CARYR in table T511K. However,this constant does not exist at the moment.

System Response
An error is output and the valuation is canceled because the systemdoes not have the data it requires to perform the calculation.

Procedure
Enter the number of years that elapse before the change of rules occursas constant CARYR in table T511K.
