FPY1 run does not clear open items

Hello Experts,

I was paying for BPs open recevable via FPY1,application log also go green no error.I assumed paymnet done.

But when I see FPL9,still item is not clear,so my doubt is some configuration missing, but why it is not shown in application log.

How I will go to root cause of error ?

Thanks & Regards

Amit
