Hi

For Model node we will bind the Model attributes to the backend retrive from the R/3 or ECC.

Model node purpose is retrive actual data of the Application.

For Recursion node We will use at the time of creating Tree structure and creating packages.

We will bind the values the values to this node. At runtime , it will display like Tres structure.

the Differnce between Model node and Value node is :

Modelnode followed passby Ref concept(in java)

Value node followed by Passby Values concept(In java)

I hope its clear now

Thanks
