How to make a Normal function module to RFC fm.

Hai All,

I have developed some Custom Function Modules for making DML operations on Ztables. Now My requirement is to make them RFC enabled so that they can be accessed through Java( as one of my collegue wants to access R/3 Database through Java).

Can you list all the requirements?

Some I know are

1. parameter reference to be made to dictionary types only

2. parameters to be passed by value only

is there any other requirements?

Thank you in advance
