Since you are calling your PCR with function PIT and are using Par2 = NOAB, you should have all WTs listed in your PCR, such as in this one :
Note that we use operation VALEN as we can base our decision on the first 2 characters of the PA, but that you probably would not use it.
Do a Payroll Simulation for one employee, with the "Display log" box checked. Once you have the log on screen, drill down until you find your PCR (A000) and double click on it.
You will be able to see what WTs are in the Input Table, and with what values, and you will be able to see how each WT is processed, and what is the Output (Input Table) after processing.
