My scenario deals with HTTP to Synch Proxy. In synch Proxy I am call an RFC. When I testing Synch Proxy from SPROXY it is excuting sucessfully. When I am testing from HTTP test tool it is giving HTTP_RESP_STATUS_CODE_NOT_OK-500. It is throwing short dump in System "Y" where synch Proxy exists. The short dumpe error is function module "RFC_START_PROGRAM" not found. And the pointer in short dump point to the statment at
call function 'xyz' destination lv_dest. I notices that proxy is taking so much time and it is throwing internal server error. If scenario takes a small time means scenario works fine.Plz suggest on this.
