Call Inbound Proxy error

Question

PI settings help
I am trying to transfer PR from ERP6.0 EHP4 to SRM7.0 using CPPR scenario.
I configured ERP/SRM and PI configuration in Integration directory.
But i get Reciever determination error in XML at ERP/SRM AND PI
RCVR_DETERMINATION">NO_RECEIVER_CASE_BE
Error Text: No receiver could be determined
In SRM, Inbound Message(reciever) is green but Call Inbound Proxy is giving below error.
<Trace level="1" type="System_Error">Application-Error exception return from pipeline processing! <Trace level="1" type="T">Application Error at Receiver... => ROLLBACK WORK</Trace>
<Trace level="1" type="T">System Error at Receiver... => ROLLBACK WORK</Trace>
I tested configuration in Integration directory.
Sender aggreeemnt is green
Reciever determination is red and giving below error.
Internal Error : You do not have sufficient authorization for this operation.
I have done below setting in Integration directory.
Business system setting.
1.Selected Business System BC_MM_MXX_594
2.Create communication channel(Gen_Rec_xi) as Receiver
  for above Business system BC_MM_MXX_594.
  -Use adapter type XI, http://sap.com/xi/XI/System SAP Basis7.xx and RFC MXX_Integration,
1.Selected Business System BC_SRM_SXX_300
2.Create communication channel(Gen_Rec_xi) as Receiver
  for above Business system BC_SRM_SXX_300.
  -Use adapter type XI, http://sap.com/xi/XI/System SAP Basis7.xx and RFC SXX_Integration.
-->>one doubt here? Should i have to create Comm channel for sender type also from ERP and SRM? pls confirm.
I created object in Integration directory as follows.
Create Object by selecting Business System BC_MM_MXX_594.
1)Selected Internal communication
2)Reciever Determination : BC_MM_MXX_594 PurchaseRequestERPSourcingRequest_Out
3)Specified Interface determination : BC_MM_MXX_594 PurchaseRequestERPSourcingRequest_Out BC_SRM_SXX_300.
4)Specified Reciever agreement BC_MM_MXX_594 BC_SRM_SXX_300 PurchaseRequestERPSourcingRequest_in(communication channel selected is Gen_Rec_xi)
5)Generated Objects and saved as CPPR_scenario.
6)Activated all objects created in CPPR_Scenario.
Pls suggest something wrong with Reciever determination?
How to find where the problem is located? at ERP or PI or SRM?.
Also onething i noted is Integrated configuration is empty in Integration directory.
Any configuration should be done for IOC.? pls confirm.

Answer 1

Also i noticed below
In ERP xml ->Inbound message(SENDER).
Does this error indicate problem while sending from ERP to SRM or SRM to ERP.
because i can see sender service and interface is empty and SAP reciever is having ERP service.
however reciever does not fetched the corresponding(purchaseRequestxxxxxxx) interface names.
