Poland VAT split payment

Hi,

I have done the all configuration setups as per the oracle document.

Payment method

Pay group

Payable lookup code

Split bank account with local currency

I have attached the split bank account to supplier site level , Created the foreign currency invoice for Poland and installment level i have provided the pay group and manually split the net value and vat value and made the payment.

I have check the payment history VAT amount paid USD currency not in PLN.

Installment level it will not derive automatically we need split manually?

Need to understand how it will work, can you please suggest me anyone.
