UDF PO ROI to AP_HistoryHeader & AP_TransactionPaymentHistory

SOLVED

I created a Date UDF in PO Receipt of Invoice. it populates correctly. I'm trying to get this data into the AP_InvoiceHistoryHeader & AP_TransactionPaymentHistory.

I've tried several links and can't seem to get the correct combination.

Can someone tell me from PO_ReceiptHeader how I walk it through to these other 2 tables?
