I tried to build IDOC to File scenario using AEX in PI 7.3.But,when we tried to test the scenario from runtime work bench Adapter Engine we are facing the below issue
Error While Sending Message: Additional error text from response: com.sap.engine.interfaces.messaging.api.exception.ConfigException: ConfigException in XI protocol handler. Failed to determine a receiver agreement for the given message. Root cause: com.sap.aii.af.service.cpa.CPAObjectNotFoundException: Couldn't retrieve outbound binding for the given P/S/A values: FP=;TP=;FS=C1D_110;TS=;AN=ORDRSP.ORDERS05;ANS=urn:sap-com:document:sap:idoc:messages; in the current context [Unknown]. “.
