CALL_FUNCTION_SEND_ERROR

8250 Views

Hi Experts,

Getting CALL_FUNCTION_SEND_ERROR in production environment. Around 20,000 users are affected by this issue. This particular exception is raised when the user try to connect from third party tool to SAP. And to be specific this happens only when they try to connect to a particular custom function module.

I have gone thro' many threads and checked SM21 system logs. I have attached the same for reference.

In many threads they have mentioned "Connection to the partner '' broken (I/O) is specific to network issue. But our question is why it is occurring only when it is trying to connect to this particular custom function module?

Actually this particular FM is a wrapper FM which is present in our portal system. The error occurred at the starting point of the FM (i.e., it has not executed the code in the FM).

If any one had faced similar issue before, kindly share your inputs. It will be helpful. Awaiting for your responses.

Thanks in Advance,

Fahmeetha M
