How do I set the Transaction Code (TCODE) in a JCO program and then fetch the required function?
e.g. if I need to access SE11 or SE13 related function?
Is the TCODE setting really important?
JCO programs call RFC-enabled module function. A Transaction code is not associated with such a function (se93 will show you the type of object that can be associated with any TCode).
se11 allows to display (and modify) the structure of a table/view/structure. How do you want a RFC call on a distant server to interact with that ?
