Once you get to the Payroll page, find Action button. And click Revert Payroll.
This will reverse the payroll accounting entry. Users can also make adjustment at Adjust Salary and process the payroll as per normal payroll situation.
WHAT IF I DON'T SEE ANY 'REVERT PAYROLL' AT ACTION BUTTON?
- Most likely you do not have the Administrator role assigned to you.
- You have made payment for this payroll.
So steps to remedy this issue is by checking your user role assignment and check whether you have made the payment related to the Payroll or not. If you have, you then need to delete these payments from Bank Account Transaction page. Then the button is automatically accessible for you.
