R4702A -Understading differences

Hello,

We have run integrity reports R4702A , which print Distribution Amount -F0911 & automatic offset amount -F0911 , both amount net total become zero , but i want to know why it prints, i have checked reference document &  found this is due to difference exists between distribution amount but which i could not get, also in automatic offset there also it's shows difference exists between the automatic offset amount but which difference?

Please help me in understanding of above two things.

Thanks,
