Hi Gopalakrishnan,
I think you can use the transaction code CL30N (Find objects in classes): just input the class name and type, get the characteristics of that class, then select the object type that refers to materials (menù Extras - Restrict object types. In my system, object type is Wrk-Plant).
Press 'Find in initial class' button.
The report shall retrieve a list of materials using that class, then click the 'Change Layout' icon and select the characteristics whose values you want to display.
Hope this could be of any help.
thank you and bye,
Flavio
