I am trying to copy the FM RSAX_BIW_GET_DATA_SIMPLE to a Z FM name for function group RSAX. For some reason, it gives me the info message "Function module name is reserved for SAP". When I click on to continue, I get the prompt to register the object. How can continue to create my own FM without having to register the object? Does this mean that I have to register the function group RSAX before I can create my own FM?
Please advise. Thanks.
