Advance payment against PO, book advance payment in Tally then capture bank ref code in advance payment?

We have a requirement where in I create a PO of say Rs 50,000, I need to pay advance to supplier of Rs. 35,000. We want to first send a payment advice to our bank for the advance amount and later create a payment entry of the payment made along with its bank transaction reference number.

Is there a way in ERP Next to generate the payment advice/remittance advice to be sent to bank.
I saw that for advance entry we create a Journal entry, I believe its made post payment is made, I want a document which I can create before advance payment is made and later update the same document with bank reference number for the payment.
Please suggest how to go about using ERP Next.

Did you try Payment Request?

Please check if it could be made for the party like Bank.
