After CRM upgrade RFC s are not working
After CRM upgrade from 6.0 to 7.02, RFC s are not working. CPIC Fail. Error when opening an RFC connection. Please help ASAP. Also, in SM59, RFC callback CHK not secure error.
I changed the parameter rfc/callback_security_method to 3 and restarted SAP. All RFCs started working. This is new parameter from upgrade.
