RFC sender adapter error
My Communication Channel monitoring shows this error for my RFC C.C.:
Error in processing caused by: com.sap.aii.af.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 'TSQCLNT300', toParty '', toService '', interface 'ZPI_FM_RFC', NS 'urn:sap-com:document:sap:rfc:functions' for channel 'CC_RFC_Sender' (channelId 80b5eda3c6ae38be8135dd698cba83ae)
I also get senderAgreement not found system exception in my TSQ system while trying to call the RFC function.
I do have a fully configured scenario with sender&receiver agreements and business systems involved, so any missing configuration should not be relevant.
What else should I check?
