Hi Nikhilaash,
- For the query about tables see arrowed portion of the PM tables picture attached to this post. You have all the tables here related to Class and Characteristics.
- Secondly, I have already posted a document on this where a code was given for a report on the subject matter. This code is based on function modules BAPI_OBJCL_GETCLASSES and ALM_ME_CLASS_CHAR_GETDETAIL . So you do not need tables if you make use of theses FMs. The document is here: ALV Report on Equipment vs Class vs Characteristics vs Values
- Also you go through another post by me Equipment vs Class Report which was done through SQVI using logical databse EQI. In this route also you might be able get your query a solution.
Above referred tables info is available at PM/CS/QM Tables for your reference in future.
Good luck
