Hi Stephanie,My initial thought is exactly what Matthew suggested, and this change is simply tied to the Employee Class setup. Having ben/ded codes change based on Employee Class does get dangerous at times, as various GP Payroll consultants have mentioned in this forum previously.
If nothing has changed with your Employee Class setup though, are you using the using the Greenshades Benefits module? If so, depending on how quickly these ded/ben codes are inactivated, it's possible this could be related to the employee eligibility in your Benefit Packages. If you think this might be the case, just let me know and I can ask our Support team to contact you about it.
