ORA-20110: InstallmentUtility.PAYINSTAL30: Amount paid (33605.00) for installment 1 of Invoice 406 is bigger than open installment amount (33605.00).

Need to offset one supplier invoice against a credit note. there was a value difference, where the supplier invoice value was higher by 40 than the credit invoice. Therefore, I raised another credit invoice to tally amounts. but still the system generated “ORA-20110: InstallmentUtility.PAYINSTAL30: Amount paid (33605.00) for installment 1 of Invoice 406 is bigger than open installment amount (33605.00)” error message.
To test a different way, I lowered the invoice amount by doing a mix payment to tally amounts with the credit invoice, but the system generates the same error message.

Any suggestions to sort out this issue?
