Payroll Overpayment

Hello,

Wondering if anyone might be able to help me.

I've overpaid an employee by a few hours on his last pay. We have invoiced him for the net amount as per CRA guidelines, but how do I adjust this on his employee activity? 

I think I need to add a transaction history entry, but am not sure how or if that's what I need to do.

I need to ensure that the adjustment is reflective on his ROE & T4.

Thankful for any help!
