Incompatible Objects in Designer

Hi,

I am having 4 Folders(classes) in my Universe, how to set incompatible objects.

Ex:

Folder1:

Folder2:

Folder3:

Folder4:

Compatible folders(combination):

1-->Folder1 & Folder2

2-->Folder1 & Folder3

3-->Folder1 & Folder4

If i selected one object from Folder2 & another object from Folder3, then it will show incompatible objects

If i selected one object from Folder3 & another object from Folder4, then it will show incompatible objects

If i selected one object from Folder2 & another object from Folder4, then it will show incompatible objects

Please give me solution.

Thanks,

N Praveen
