using function modules

[Former Member]

Hi all...

My doubt is that , that is there any procedure to know how to use a function-module...???

( i.e:- by seeing the function module, knowing what input parameters and output parameters to be passed )

If you know the function module name ,Go to SE37 and provide your function module name click on display.in application tool bar you can find the Function Module documentation.Click that one to display,it will guide you how to use this function module.

If you are beginner ,just create a function module with IMPORT PARAMETERS : X

Y

EXPORT PARAMETERS : Z

in Source Code Provide you code as Z = X + Y.

Acticate the function module ,now put break point in your source code and excute then you will come to know how a function module will perform

You can go through the FM documentation , if available .

Else go through the code.
