Summary

Team-Fly

The first time you set up a function module call in Java, you have to write a fair amount of code. However, you will find that all calls follow the same pattern and that you can set up methods within your Java class to perform the repetitive coding operations.

One key to a successful Java program is efficient operation. Efficiency is accomplished by setting up only the parameters that you need and by using the correct calls; these techniques avoid as much overhead as possible. You also want to catch and print out or log all errors that occur when you first start setting up RFC calls. Reviewing these errors will often tell you exactly what is wrong with your program or your setup to the function module.

Data structure is the most important thing to understand when working with RFCs. ISimple fields are the basic ones; they are used to develop the structure and table parameters. Chapters 19 and 20 provide detailed information on the methods that are available in the area of constructors for the data, along with methods that are available for the data and IRfcModule interfaces.
