We experienced a strange phenomenon in BN32.1 where some Health Savings Account and Flexible Spending Account plan enrollments terminated 11/30/2020 either due to voluntary cancellation or contribution change. However, the deduction was duplicated, which meant another deduction record with the same start date as the corresponding benefit record was created ending 12/3/2020, The original deduction record ended 11/30/2020 as expected. The affected employees had deductions or duplicate deductions in December where they should not have, I've no clue what caused this issue much less how to prevent it. I do know how to correct it when it is caught PRIOR to payroll processing - delete deduction cycles. Has anyone experienced this situation? Thank you.
