Message Mapping of type ABAP Class not being shown

Hi all,

I have been trying to follow the given blog:

/people/ravikumar.allampallam/blog/2005/02/10/different-types-of-mapping-in-xi

Even after doing the changes mentioned in the blog, i do not see the ABAP Class in the list of Message Mapping types.

Do i need to do anyother configuration. Pls guide.

Regards

Neetu
