Past payruns done before the changes were implemented will not be affected, but all future payruns done will have those changes in place. If you wish to effect the changes on past months’ payruns, you would need to delete and re-run the affected payruns once more. To learn more about deleting payruns, click here.
However, kindly note that if you are making changes for previous payruns, the Year to date (YTD) value that you see will take into account the amounts for the other payruns done before. For more information on the system’s calculation for YTD values, click here.
