Hi Rajesh,
What is the tolerance day(s) you have mentioned in "Prepare Item Interest Calculation" configuration. Is it 2 days?
IMG > A/R and A/P > Business Transaction > Interest Calculation > Interest Calculation Global Setting > Prepare Item Interest Calculation.
Also please advise if the payment term is defined in in your item interest configuration, then what is the default baseline or Baseline date Calculation. If possible please provide the screen shot of the same.
Please confirm
Thanks
Naseem
