If you look at your error message, it happens during processing of function PIT, where Par1 = X025 and Par2 = P04 (and Par3 = NOAB). Here, the second parameter implies that Processing Class 04 is the main processing criteria, and Venkatesh Yadav mentioned that you should check the value of Pr.Cl. 04 that is used for WT /127.
Look at the PCR to see what values are processed and which ones will generate an error (it could vary depending on your Country Code), make the appropriate correction and repeat the Payroll simulation.
