What I have found is the best method for doing this is actually adding a row inserted/updated event inside of the Posting Graph (INReceiptEntry in this case) that links back to the originating document (PO Receipt)
Here is the following pseudocode:
So inside the INReceiptEntry graph
INTran Row Inserted / Updated
If POReceiptType, POReceiptNbr have a value
Get the Receipt header from those values
Get the current INReceipt header for this INTran
Get the extensions for both and copy the values between the two.
