Hi Santoshpratim,
I would not recommend such an approach. The most safe and standard approach is to use the Rule Groups which can be considered as "logical update groups". Characteristics and Key Figures which belong together are processed as a group. This is easier to understand and makes it less complex.
You are of course free to experiment which an alternative approach. I suggest to try it out how easy or difficult it is. In this case you should work with only one Rule Group, next the Standard Rule Group. Maybe the best way is creating a new Transformation so that you keep the Business Content Transformation as backup and reference.
Please test carefully and pay a lot of attention to the data consistency.
Best regards,
Sander
