Error is Receiver AS2 adaptor used for Idoc to AS2 scenario

Question

Hello Experts,
   I am doing Idoc to AS2 B2B scenario where I am getting below error message in runtime workbench comm channel monitoring.
Message processing failed. Cause: javax.resource.ResourceException: Fatal exception: com.sap.aii.af.ra.cci.XIRecoverableException: SEEBURGER AS2: AS2 Adapter failure # Outbound configuration error: Sender configuration incomplete - perhaps AS2ID missing.., SEEBURGER AS2: AS2 Adapter failure # Outbound configuration error: Sender configuration incomplete - perhaps AS2ID missing..

Basis has already configured the AS2 Server with Certificates and provided me the below details for receiver agreement and those are put in Receiver agreement.
AS2 sender Configuration:
Authentication certificate à TRUSTEDAS2certAS2_datapool
AS2 Receiver Configuration:
Decryption Key à TRUSTEDAS2certXXXenterprise2008
Signing Key à TRUSTEDAS2certXXXenterprise2008
XXX is my receiver partner
For the Receiver party XXX I have maintained the Identifier as given below
*Agency----
Scheme-------Name*
http://sap.com/xi/XI--XIParty--
XXX
Seeburger----
AS2ID----
XXX_AS2ID
There is no need for sender agreement for Sender IDoc but still I tried to created R3 as sender party and R3 Business system, used it for the scenario and created sender agreement for sender Idoc but received same error message in Runtime workbench.
R2 system sender party is also set with identifier with AS2 ID.
MDN mode is set to no MDN in the receiver AS2 communication channel.
Please suggest me if something is missing or wrong in the configuration.
Thanks in advance.

Hi Larry,
   The solution was very simple.
It was problem with the basic understanding of system and configuration.
Idoc is send sent by R3 ERP system and target is Partner Party. As ERP system is Business system and not the party w.r.t XI/PI terminology, we are not supposed to use Sender party as Sender ERP system but just use Business system as sender without any sender party. So in this way PI system could recognize that the data is coming from R3 system which is nothing but PI Business system.
Now question comes where to user the Serder Party which was defined with AS2 ID? So answer is in the receiver determination we have to mention the Sender party and sender service in the header mapping part (Also mention receiver party and service).    
So in my case problem was with sernder party. I mentioned sender party in all receiver determination, Interface determination, Sender Agreement and receiver agreement where only sender service ie sender system was required. And as I configured my scenario without sender party it worked because PI could recognize the sender R3 system and AS2 ID was recognized form the Header mapping of Receiver Agreement.
Kindly let me know if it works and if you require snap shots of my configuration then I can send you the same.
