Cancellation GR amount different than GR amount

Hello Experts,

I am facing an error that the GR was done a few months back with amount 3,85,75,129.29 and when the cancellation of GR was done it was being done at 3,85,75,129.30.

The values shown above was in USD and the same 0.01 difference was there in local currency.

Can you please tell me why is there a difference of 0.01 in GR and GR cancellation.

Waiting for the reply!!

Regards

Abhi
