No Receiver Agreement found - IDOC RCVPRN = Party

Question

Hello,
I have created all the receiver agreements required and they are in the configuration scenario. 
I have a receiver determination that is using the IDOC vendor number (RCVPRN) to determine the party for delivering purchase orders and another RD with the same config for delivering po changes. 
In tests my POs are sending successfully and my PO Changes are failing even though they use the same party setup/config.  In SXMB_MONI I can see that the receiver determination for the POs are creating the correct party:
PO Results:
<SAP:Party agency="http://sap.com/xi/XI" scheme="XIParty">Ventura</SAP:Party>
But the PO Changes seem unable to connect the vendor number to the party:
PO Change Results:
<SAP:Party agency="http://sap.com/xi/XI" scheme="XIParty">0000557129</SAP:Party>
In the sample above the party Ventura is set up under the party identifiers as follows:
Agency:
http://sap.com/xi/XI
http://stc.com/pi/SAPR3
Scheme:
XIParty
Vendor
Name:
Ventura
0000557129
How is it that PI 7.10 is getting the same value in RCVPRN and assigning the Party correctly in one case and incorrectly in another?
Any ideas?
Thanks,
Matt

Sometimes you just need to walk a way for a day or two...  I rechecked the standard configurations over and over.  But I didn't review the Party Extended selection.  In the Receiver Determination I chose to use RCVPRN to identify the Party but upon further investigation I realized I was using the wrong scheme and agency on the Party extension.
So my party had the following:
Agency:
http://sap.com/xi/XI
http://stc.com/pi/SAPR3
Scheme:
XIParty
Vendor
Name:
Ventura
0000557129
My Receiver Determination was not using http://stc.com/pi/SAPR3 Vendor 0000557129 to determine the Party it was attempting to use http://sap.com/xi/SI XIParty Ventura.  So it was unable to find a matchinig party using the Vendor Numbers.
Thanks for all the help.
