Adding messages to payslips

Hi

We need to include some messages on the payslips for all employees and I’m looking to achieve this using standard functionality if possible.

From what I can see the standard UK payslip (PayslipUk2.rdl) includes 2 message fields, COMP_MESSAGE and  EMP_MESSAGE.

I believe EMP_MESSAGE is populated using the M001 parameter in Emp Data Const on the Payroll Information screen but I’m struggling to find out how the COMP_MESSAGE value is populated.

Does anybody use this functionality or happen to know how it works?

Thanks
Anthony
