Down payment request fields into F110

Hi,

We are posting down payment request with transaction F-47 where users enters data into fields

Reference Field(XBLNR) - Vendor name

Doc. Header text (BKTXT) - PO Number

After F110, in the payment entry, both the fields should be copied from down payment request document.

Currently, both the fields are blank in the payment entry.

How to get copy data from these two fields into payment entry?

Thanks
