Employee does not (yet) have a BSN (social security ID)
When an employee does not yet have a BSN, you normally cannot register the employee or submit changes via eveHRyday. The workaround for this is to enter 000000000 (nine zeros) in the BSN field. In Nmbrs Payroll, you will receive an error message regarding this when starting the payroll run; you can then remove the BSN. During the next synchronization, the BSN in eveHRyday will be cleared again, so you will have to repeat the above steps to implement new changes.
