Hi,
Could not understand some where you don't want to take from RT table.
See if you want to show the LOP days in the payslips then you have to pass the LOP days to wage type which will be passed to RT table. Hence you are saying that it's passing to RT then check its stored as amount or number. Based on that design your window section for LOP wage type (days) or Line.
Share the RT table details. Since if cluster is not updated then it would not be updated t op Payslip so before getting the output in payslip, RT table should be updated.
