Hi Rohan,
As you know WT /560 is Retrocalc.difference and you won't have it in main scenario of payroll run. System generates this WT when the difference is positive otherwise you will have /561.
It's better why you have this WT first then you can make a decision about correcr PC.
Please find more information about retro.calc. in my replies at
