SLDAccess set to true, but not available - http to RFC Scenario

Hello Experts,

I have created http to RFC scenario in DEV system and it is working fine.

But after transporting the scenario to QAS system. It is giving following error.

com.sap.engine.interfaces.messaging.api.exception.ConfigException: SLDAccess set to true, but not available

Please advice on this ...

Thanks ,

Vishal
