RFC call ended with "Communication Failure" exception in Gateway Service testing?
Our current Landscape of Gateway is "Central HUB Deployment" where all the Gateway Add-on's installed on Gateway Server. i.e. IW_FND, GW_CORE, IW_PGW and IW_BEP is also installed on Gateway System.
As IW_BEP is installed on Gateway System, we are doing gateway development in Gateway system itself by creating Remote-Enabled Function Modules in Backend ECC system if no standard BAPI or RFC function module is not available and if available using the standard itself.
In Gateway Development, we are using Remote option to access the Function Module and on top of those function modules/structures we are creating all the gateway services in SEGW T-code and registering the service by Selecting the Gateway System (GW_HUB system alias) and providing the Backend System alias in the followed pop-up where it asks for System Alias.
System Alias for Gateway system is : GW_HUB
System Alias for Backend system is : ECC
Now we are trying to test the service, getting the below error.
Can anyone please suggest me how to solve the above issue.
Thanks in advance.
