3PR evaluation

I am unable to do 3PR posting of an employee as I get the message- payroll results already evaluated FURMIT when I run u500 schema. I see that the payroll results have retro accounted to few periods back. I can't delete the results too as it is already posted in another run. The current run is an off-cycle run. I tried to put a soft stop via ity3 but system is bypassing it. Please help. Pretty please...

Thanks,

Dolly
