2726888 - PO interface error after executing Full Cache refresh

• You have a Process Orchestration (PO) system with multiple Integration Flow (Iflow) or Integrated Configuration (ICO) interfaces
• You have also configured at least one "Wildcard ICO" (see note 2277886) which is also working fine.
• If you execute a Full CPA Cache refresh, then these interfaces may stop working
• In this case, we are documenting the error from an ABAP Proxy -> PO scenario using SOAP Sender channel in XI 3.0 mode
• If you take the XPI Inspector Example 50 (By Channel) trace you will see an error like: 
  com.sap.engine.interfaces.messaging.api.exception.ConfigException: No sender agreement configured that matches the message's header fields 
  com.sap.engine.interfaces.messaging.api.exception.ConfigException: No sender agreement configured that matches the messages header fields
  
  
• The error visible in transaction SXMB_MONI in the backend proxy sending system is similar to below:
  <SAP:Code area="INTERNAL">CLIENT_RECEIVE_FAILED</SAP:Code>
  <SAP:P1>Configuration error on Adapter-Framework(AFW)-Server</SAP:P1>
  <SAP:P2>com.sap.aii.af.service.cpa.CPAObjectNotFoundException: Couldn't retrieve inbound binding for the given P/S/A values: FP=;TP=;FS=<Sender_Component>;TS=;AN=<your_interface>;ANS=<your_namespace>;</SAP:P2>
  <SAP:P3>Please check configuration for SOAP/XI sender agreement</SAP:P3>
  <SAP:P4/>
  <SAP:AdditionalText/>
