Call Inbound Proxy error

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.
