Hi Experts,
We are getting CALL_FUNCTION_SEND_ERROR while it is trying to call a custom function module in production environment. We are not facing any kind of error in staging system.
In ST22,we could see that the dump has occurred at the start point of the custom function module.
In the short text we could see the text "Connection to partner broken" (I/O error). Is it anything related to the custom function module ?
