I am not family with a Gross to Net like report in HRMS.  I will respond for the Sage Abra Suite product. For any earnings that should be premium pay and they do not appear in the Premium Pay column on the Gross to Net Summary report, verify the earnings are set up as Premium Pay.  Path:  Setup > (Codes) Payroll > (Earnings/Deductions/Taxes) Earnings > Select the level where codes are being read from Employer vs Enterprise.  Detail the earning code that is incorrect.  Verify the Earnings Type field.  It can be set to Base Pay, Premium Pay, Tax Only not in Check or Not Pay (Reimbursement).  Perhaps it is set to Base pay when you want it as Premium Pay?
