Rebate Accruals roundings

Hi Experts,

please can you help me with Rebate accruals?

Total accrual value calculated into Rebate from invoices processing, is slightly different (roundings problem) from final value of credit note to be granted to customer.

Currency is always EUR.

Can you help me please to find out if it is pèossible to have the same value for both?

Thank you very much

Kind Regards

Andrea
