Procedure
RESET N1
If you want to deduct a fixed monthly payment for your insurance, itcannot be done in connection with a maximum wage limit becausethe employee's wage has no influence on the contribution amount. Inthis case, you can can store an amount insured, which is merelyinformative. This amount can be, for example, the amount insured in theevent of death. You can, however, leave the field "delimitation" blank.
If you want to insure a fixed amount insured, for example, credit inthe event of death, you must store the monthly insurance contributionsof the employee and the employer as fixed amounts. The amount insuredis merely informative and is not used for calculations. A dependenceupon wage totals only occurs when the contribution for the lowercontribution level is calculated proportionately for maximum wage X. Inaddition, the monthly contributions for the current contribution levelare only deducted if the employee's wage lies above the lowercontribution level's delimitation. In this case, you must set theindicator for a contribution calculation based on the differencebetween delimitations.
