HI. I got the following error.

Error in processing caused by: com.sap.aii.adapter.rfc.afcommunication.RfcAFWException: senderAgreement not found: lookup of binding via CPA-cache failed for AdapterType RFC, AdapterNS http://sap.com/xi/XI/System, direction INBOUND, fromParty '*', fromService 'TEST_SYSTTEM', toParty '', toService '', interface 'TEST_INTERFACE', NS 'urn:sap-com:document:sap:rfc:functions' for channel TEST_CANNEL(channelId a85e12f4cb943f0a8f08ae14df39ce4f)

Anyone know how to solve this problem?
