Hi,

 

I have this simple Payroll element balance look up that is not capturing the negative balances that are recorded when you reverse or void a payroll payment. I know that there are out of the box reports like the Element Result Registers and the Deduction Report that do this as part of regular functionality but due to how our security is structured, we will not be granting access to those OOTB Payroll reports to the users of this report. The XML for my lookup is attached.
