Hi @Nagarjuna ,

Go to supplier payment window and add a new entry.

Under the general tab enter the cash account and enter the amount

Go to transactions tab

Add a new entry

Select the check box New Payment on Account (The checked box indicates that it is a new payment on account entry.)

Then you can enter the supplier and the amount.

Save the window > RMB > Approve. A voucher will be created.

Thanks and Best Regards,
Rashen
