CMN.ATO.PAYEVNTEMP.000239 .Cessation Reason Code must be provided
For Single Touch Payroll (STP) to properly finalize terminated employees, all terminations must be processed within a pay. Simply entering a Termination Date and Reason under an employee’s Dates tab is insufficient.
To address a finalization error that occurs after processing a termination in a pay sequence, please follow the steps outlined below to resolve the issue:
Open a Manual Pay.
Adjust the Payment Date to 30/06 of the relevant financial year. To do this, access the transaction view, select the sequence, navigate to the employee, and press CTRL + A.
Add the Termination allowance.
Verify there are no payments included in the pay. If any payments appear, override them by entering 0.00.
Process the pay using the appropriate option in the menu.
Close the pay.
Refinalize the employee(s).
