In Nmbrs you can use the time registration to input scheduled events (sickness, paid leave, parental leave etc.). These events will show on the payslip. 

On masterlevel and debtorlevel you can add a time registration model by clicking on 'new time registration model'.

When you created a new time registration model you can add the codes by clicking on 'time registration types'.

When you save the selected codes they will show in the selected time registration model. The model has to be linked to the used labour agreement for the company.
