It only occurred to me right at the end of writing my question that SAP like to have five or six totally disparate components, all doing utterly different things, all with the exact same name. It is like Heathrow airport in the UK where there are two hotels nearby, both in the same street, both having the exact same name, and they cannot for the life of them work out why they keep getting each others mail, or having each others guests turn up.
I know you do not decide what names components are called, so I am not having a go at you, but you have to admit it is rather silly to call lots of different things the same name and then not expect people to get confused. As Einstein once said "there are only two things that are infinite - the universe, and human stupidity. And I am not sure about the universe". We have multiple application servers on SAP.
The only issue is that if the server mentioned in the Gateway Host goes down for reasons like Rolling kernel Switch etc,The external application wil not be able to connect. Yes, on section " Getting Program and Gateway details on SM59" if you see exactly this example on item 4 picture, there is no Gateway defined on "Gateway Options".
When this information is blank, this destination can use any Gateway from system to communicate with the program. So, even if one instance is down, the rest of the instances will keep online and having the TP program registered. Such system could provide a way to register the program on a list of instances, but this is not mandatory.
If we are talking about a third-party non-SAP system, then you should contact the support team of the system. If it is an SAP system, you can search for documentation help. This is exactly the purpose of this blog.
As documented on SAP note The RFC connection tests were successful only while rfcexec process was running. Otherwise, the RFC tests fail with error "program not registered" If the rfcexec is only for testing purposes, then I'm a bit confused. What does "program registration" actually mean?
In this testing scenario rfcexec has role of RFC server. It is registered at particular gateway, it technically means that network socket connection was created between RFC server actively running rfcexec and the gateway.

We apologize for the inconvenience. Arthur Wurth. December 8, 4 minute read. After reading this Blog, the following skills will be acquired: Definition of a Registered Program. Identify Program ID and Gateway from of a destination.
Find the appropriate team to provide programs registration steps. Understand Gateway security rules. Test and validate if a program is able to be registered.

The arguments I am facing in favour of RFC function modules instead of Gateway are as follows:- it RFC works and it is easy all the other source systems are contacted directly and contacting Gateway is contacting "middleware" instead of the actual source system, thus giving one source system special treatment instead of treating all source systems the same the call to Gateway will introduce two more HTTP calls in addition to the original one from the device, thus negatively effecting performance, and making t more difficult to pinpoint any point of failure Gateway cannot do an asynchronous call Now, I would like to tell me that these arguments are nonsense, and give me some cast iron reasons I can use to knock holes in the proposed plans.

Hello Sam, Thanks for your question. The pre-requisite is registering the program in all Gateways of the system. In the C program, we have a function module. But we have a issue. Is there any step we are missing? Do we need to register the RFC using some command in the window server?

This was because I have mentioned this in a whitepaper that I have published a while ago in whithout describing in detail how to do it.

Atul Mohanty. Hi Andre, Hope you are doing good. Please note, when we are using a existing RFC for a different connector in the system it works. Could you please guide us on this issue? Thank you. Regards, Atul M.
